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

HAL_ChibiOS: use a non-blocking lock for UART shared DMA
...
we can have multiple UARTs on the same thread sharing the same DMA TX
channel. That can lead to deadlock with blocking locks on DMA. This
makes UART requests for DMA locks non-blocking to fix the issue

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
