drivers/serial/uart_16550.c: Add a configuration, analogous to the STM32 configuration option, to suppress the NuttX standard re-ordering for /dev/ttySN for special case of the 16550 UART.
config/serial: UART 16550: Add CONFIG_SERIAL_UART_ARCH_MMIO option so the a memory mapped device doesn't need to provide uart_getreg() and uart_putreg() implementations.
u16550_txempty() should check UART_LSR_TEMT to avoid some data left in the transmit FIFO

kinetis:Add DMA and use it as RX FIFOs on Serial
* 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
and friends.
2. Prefix arch specific featurs as such
UARTx_RXDMA->KINETIS_UARTx_RXDMA
* Kinetis:Serial formatting and clean up
* kinetis:DMA Formating and Cleanup
* kinetis:serial Use cleaner DMA API
* 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
* freedom-k66f:Disable Serial RXDMA
The application has to add calling of the kinetis
serial dma poll as it is application specific.

configs/lc823450-xgevk: Update defconfig for krndis
Enable SCHED_CHILD_STATUS and SCHED_HAVE_PARENT
Change IOB related params which are the same as rndis

Fix http streaming with lc823450
* arch/arm/src/lc823450: Change C-Buffer under-level control
The under-level setting was changed from 1KB to 55KB.
In previous implementation, the setting can ben changed
by the tx threshold but it is fixed at startup.
Also, check write size and adjust alignment if needed.

* configs/lc823450-xgevk: Change IOB related params for rndis.
Since TCP flow control scheme was changed, HTTP audio streaming
has not been working. These IOB params are not optimized but
HTTP audio streaming now works.
