HAL_ChibiOS: added a timeout to DMA UART TX
this prevents a shared DMA channel being held for a long time if a CTS
pin is held either by not being connected or by a radio

HAL_ChibiOS: make smaller builds possible
this allows for much smaller builds when you disable a lot of
options. This is part of an effort to create a bootloader of less than
16k using ChibiOS

HAL_ChibiOS: support DShot output
use DMAR burst DMA to minimise number of DMA channels needed
thanks to betaflight for the great reference implementation!

HAL_ChibiOS: make UARTs non-blocking by default
we never want blocking ports any more with ArduPilot, so defaulting to
blocking makes no sense

HAL_ChibiOS: allow for bare board builds
this allows for a build with no UARTs, no SPI, no I2C, no PWM. Great
for initial board bringup with just USB

for unbuffered uarts

HAL_ChibiOS: implement low latency UART writes
this implements the set_unbuffered_writes() API by performing writes
directly in the write() call and not from a timer

HAL_ChibiOS: rename classes to remove 'Chibi'
it is redundent as all classes are in ChibiOS namespace, and makes the
code harder to read
