stm32f7: serial: Fix ioctl TIOCSSINGLEWIRE
The TRM notes that UE must be disabled in order to write HDSEL in
USART_CR3. This was not being done, so calls to TIOCSSINGLEWIRE were
silently failing.
This change checks the state of UE in USART_CR1, clears the UE bit
before writing HDSEL, then re-enables it if neccesary.

* stm32f429i-disco: Fixes eliminated register control by compiler optimization
When reading 1 byte from the SPI device the clock must be enabled and
immediately disabled. This section has been optimized by the compiler (-O2) to a
missing active spi clock. A subsequently block read failed because of missing
response from the spi device. This has been lead to a broken display
initializing.

Signal handlers maybe run with interrupts enabled or disabled, depending on how the task the received the signal was blocked. (i.e.: If sem_wait() is called, then we disable interrupts, then block the currently running task). This could be dangerous, because user code would be running with interrupts disabled.
This change forces interrupts to be enabled in up_sigdeliver() before executing the signal handler calling up_irq_enable() explicitly. This is safe because, when we return to normal execution, interrupts will be restored to their previous state when the signal handler returns.

arch/arm/src/stm32/stm32f10xxf30xx_flash.c: Re-implemented Dmitriy Linikov's change to support multi-banked FLASH on the STM32 F1 parts AFTER separating the FLASH support by architecture and implementing more standard base+offset register addressing. Now the change goes in rather cleanly.
arch/arm/src/stm32/stm32f10xxf30xx_flash.c: Use base + offset address to simplify implementation of dual bank flash.

Kinetis UART must be placed in 9 bit mode (M=1) with when 8 bit
data with parity is required. If left in 8 bit mode (M=0) with
parity then D7 of the TX/RX register becomes parity bit. Hence
what is called 9-bit or 8-bit Mode Select is a misnomer.
8 bit mode when parity is enabled is realy 7 bit with parity.
Previous BRFA was not cleared and or-ed into new BRFA, hence
buadrate was wrong. Where Baud Rate Fractional Divisor (BRFD)
UART baud rate = clock / (16 * (SBR + BRFD))

arch/arm/src/imxrt: Add cache operations to permit the Ethernet driver to work with the D-Cache enabled, at least in write-through mode.

arch/arm/src/imxrt: The Ethernet driver is now functional, at least with the D-Cache off. The final fix was for the reference clock that needs to be forced to provide and input (SION).

Fix trivial coding standard issue.
configs/imxrt1050-evk: Correct CONFIG_RAM_SIZE in all configurations (5Kb not 5Mb). I don't believe that CONFIG_RAM_SIZE is used at all in the i.MX RT so this is as grievous an error as it seems. Also enabled built-in applications in all NSH configurations.
arch/arm/src/imxrt/imxrt_enet.c: Trivial and cosmetic.
Cosmetic update to comments.
arch/arm/src/imxrt/imxrt_enet.c: Oops.. put the PHY interrupt init hooks in the wrong place. That is a one-time initialization but imxrt_initphy() is called on each ifup.
arch/arm/src/imxrt/imxrt_enet.c: Add hooks for board-specific PHY initialization (not yet needed, but there when needed).
Remove dangling white space at the end of lines
arch/arm/src/imxrt/Kconfig: Add option for board-specific PHY initialization.
configs/imxrt1050-evk/src: Add basic logic to support PHY interrupts. Incomplete.. needs additional support in imxrt_enet.c to 1. call to initialize PHY interrupt features, and 2. IOCTL commands to access PHY registers.
configs/imxrt1050-evk/README.txt: Trivial update.
configs/imxrt1050-evk/netnsh/defconfig: Disable LED support because pins conflict with PHY. Enable device statists. Enable NSH ifup and ifdown commmands
arch/arm/src/imxrt: Use macros in imxrt_periphclks.h vs. direct CCM CCGR accesses in Ethernet driver.
arch/arm/src/imxrt: Misc changes for a clean compilation of Ethernet deriver. configs/imxrt1050-evk/netnsh: Add an NSH configuration for testing Ethernet.
