Squashed commit of the following:
arch/arm/src/stm32: Add Kconfig options needed by the HCI UART. Various fixes to finally get a clean error free compile with no unexpected warnings.
arch/arm/src/stm32: In HCI UART, use spin_lock_irqsave() instead of enter_critical_section() whenever possible.
arch/arm/src/stm32: In HCI UART, fix up naming of configurations so that they are unique. Still needs Kconfig settings. Modify logic so that there can be multiple HCI UARTs, some supporting DMA and some not.
arch/arm/src/stm32: Integrate watermarks and software Rx flow control into the HCI UART driver.
arch/arm/src/stm32: Eliminate some HCI UART UART configuration options. Per the HCI UART spec, the link will b 8 data bits, no parity, 1 stop bit... Always.
arch/arm/src/stm32: Trivial cleanup
arch/arm/src/stm32: Fixes most initial compilation issues STM32 HCI UART driver. Still need to set up USART configuration parmeters for HCI UART
arch/arm/src/stm32: Completes first cut at STM32 HCI UART driver.
arch/arm/src/stm32: Completes most of read logic for HCI UART. Still needs to be able to block if no read data is available. Still missing write and flush logic.
drivers/wireless: Remove txenable from HCI UART methods. arch/arm/src/stm32: Reorganize some structures in HCI UART.
arch/arm/src/stm32: Still messaging the HCI uart driver.
arch/arm/src/stm32: Some trivial renaming.
arch/arm/src/stm32: A little more HCI-UART logic.
arch/arm/src/stm32: Initial setup to support HCI-UART. Little more than the serial driver with some name changes and a few things removed.
This port was the joing effort of Janne Rosberg, Ivan Ucherdzhiev, and myself. I give credit to Ivan for the kill because he is the one to held on to the end.

configs/imxrt1050-evk/scripts: Add section to linker script to handle the case where RAMFUNCs are enabled. RAMFUNCs appear to be enabled in the default configuration ... they probably should not be enabled.
Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com>

arch/arm/src/stm32/lowputc: fix uart glitch when lowputc is enabled
Calling up_lowputc() when a character is in the shift register results
in corrupted character on stm32f1xx and stm32f205 cores.
TC status bit ensures that up_lowputc() waits for an on-going
transmission to complete before writing in TDR.
