imxrt:Clock config fixes and board.h sets sources and divisors
* imxrt:clockconfig bug fix & Board config set clocks
Fixed logic that was not clearing bits as ~ was
mising in &= mask operations.
Use valuse from the board.h file so set the Mux that
selects the clock sources.
Use board defined PODF values to select clock.
Only configure USDHC2 clocks when board defines clocks.

This change is needed specifically for the case where a bootloader sets the SPE bit before starting NuttX. In that case, the test in the SPI driver is bogus. This change fixes that by assuring that NuttX has booted and initialized at least once (whether or not SPE is set) before the driver starts refusing to initialize.
arch/arm/stm32*: Don't rely on SPI_CR1_SPE to determine if peripheral has been initialized yet.

In addition to the problems that were previously identified there were a few other bits and pieces outstanding;
* Timing was dependent on CPU speed rather than absolute time
* End of transfer handling was a bit mixed up
* It's possible for data to still be in the FIFO (i.e. not have reached
the card) when a next write is requested, so we need to wait for that to
complete
* Interrupt Status could be carried over from one transfer episode to the
next, corrupting progress
* Multi-descriptor DMA writing simply wasn't implemented, but there were no
indications ... it just failed silently

* Clocks were wrongly configured - way too fast because there is no primary divider on LPC4330
This is fixed by means of changing the definitions in the board.h file. I've edited the one for the lpc4330-xplorer board because I'm actually working with Versiboard and don't want to contribute that config just yet while I've still got the drains up on it.
* The LPC43_SDMMC_DELAY register was not being set
I suspect, in the 'real world', it's possible to get away without setting this, but I've added a register definition, default value and register access macros into arch/arm/src/lpc43xx/chip/lpc43_scu.h and then used them in arch/arm/src/lpc43xx/lpc43_sdmmc.c.
* The LPC43_SDMMC_BLKSIZ and LPC43_SDMMC_BYTECNT registers had the wrong values.
The management have already implemented a rather nice block level interface for the stm32 so I've just re-used that to write to these registers as required. I'm slightly nervous that accessing the configuration registers (SCR being the prime example) which has a much smaller block size may not be being done in the right way but it does seem to work correctly, so let's assume it's all OK until someone tells me otherwise.
These fixes have been tested with DMA-based read/write on a LPC4330. Speed via nsh is pretty low but I'm assuming that's just a buffering/implementation issue for now.

(1) Now the Ethernet is completely re-initialized when an error occurs by means of taking the interface down and back up but the PHY is _not_ renegotiated for that case because that is very time consuming and an error in the Ethernet is no reflection on the state of the PHY anyway.
(2) Explicitly sets the expected PHY address to zero (this could be moved into the config) rather than searching for it which takes ages, and it's zero anyway for this board (that's the broadcast address, and anything that cannot respond on that has multiple PHYs, so that would be a new board).
(3) Allows for the renegotiation of the PHY to be optional when a reset is needed. If a non-renegotiated reset doesn't result in good comms to the PHY then it'll automatically be escalated to a renegotiated one.
(4) Only performs a reset for errors that need it (the CRITICAL_ERROR define). The list of errors that need reset are somewhat arbitrarily chosen based on my prejudices and might need to be revisited, but certainly the jabber errors don't need reset, the partial packet is thrown away by the layer above anyway.
(5) Re-loads the multicast table on reset.
(6) Adds a bit more logging into the imxrt Ethernet module.

* Add initial implementation of the DMA
* Add across Kxx family support [WIP]
* Incorporate the DMA into the serial
Add polling to serial
do DMA initialisation at UART startup and fix DMA mux setting.
Fix circular DMA handling in the serial driver.
* Adapt defconfig to enable UART1,4 RXDMA
* [WIP] - refactor this with new CONFIG DMA settings
* kinetis/Kconfig:Bring inline with upstream stucture
1. Use the Serial console configuration from drivers/serial/Kconfig

2. Prefix arch specific featurs as such
UARTx_RXDMA->KINETIS_UARTx_RXDMA
* Kinetis:Serial formatting and clean up
* kinetis:DMA Formating and Cleanup

* kinetis:Make.defs fix duplicate/errant kinetis_dma.o
* kinetis:serial Fix warning/error on only one uart using DMA
The driver can support no DMA on any UART, DMA on some
UARTs or DMA on all UARTs.
In the case of no DMA we disable the DMA based variables
and logic. In the case of all DMA we disable the non
DMA variables and logic, and in the mixed case both
DMA and non DMA variable and logic are enabled.
* kinetis:dma config fix formatting
* kinetis:chip/dma fix formatting
* kinetis:DMA config assume Unknown
Assume KINETIS_DMA_VERSION_UKN for all SoC not versioned
This is as the code was in nuttx prior to this commit
* kinetis:DMAMUX contain versioning- use HAS pattern define Unknown
The pattern for chip versioning is to define 'HAS' constants.
Define KINETIS_DMAMUX_HAS_MONOTONIC_CHCFG to contain the
version numbers to the include soc header and use that define
in the chip headers.
Define the KINETIS_DMAMUX_VERSION_UKN for the default as prior
this commit addressing was by default monotonic for CHCFG

While this is a good idea and a proper thing to do, it also creates a circular dependency and errors during configuration. RTC depends on STM32_RTC which depends on RTC_EXTERNAL with depends on RTC. No can do.

configs/olimex-stm32-p407: Various changes as necessary to get the new kelf configuration working.
configs/olimex-stm32-p407: Add kernel ELF (kelf) configuration.
This update is required to be serialized to the instruction stream meaning that after this update completes, it takes effect immediately and no exceptions of lower priority than the new boosted priority can pre-empt execution. Because of this erratum, the priority boosting does not take place immediately, allowing the instruction after the MSR to be interrupted by an exception of lower priority than the new boosted priority. This effect is only limited to the next instruction. Subsequent instructions are guaranteed to see the new boosted priority.
This was raised in Bitbucket issue 113 from Vadzim Dambrouski.
