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: fixed SPI bus speed on SPI3
...
and add optional bootup test of SPI bus speeds to help with porting to
new MCUs

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

HAL_ChibiOS: switched to system timer for AP_HAL::micros()
...
this uses the ChibiOS system timer instead of a separate GPT timer for
the core ChibiOS timer. The advantage is it saves us a timer, plus it
changes ChibiOS to use a 1MHz clock on its timer, which gives us
higher resolution for delays.
This has a remarkable effect on timing jitter, reducing it greatly

HAL_ChibiOS: gain back 250usec in loop time
...
if we have already called delay_microseconds_boost() then we know
we've given up time to drivers, so we can avoid the extra delay in the
HAL

HAL_ChibiOS: enable I2C clearing on F412 board only
...
may be needed on other boards in the future, but for now we only know
its needed on an I2C 20789, which is rare

HAL_ChibiOS: allow for empty storage during bringup
...
useful when storage backend driver isn't written yet

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

HAL_Chibios: auto-generate I2C, SPI and UART device lists
...
this is less error prone and make a port faster as more information is
in hwdef.dat

HAL_ChibiOS: add support for CCM memory
...
this uses DMA bounce buffers for bus transfers, and falls back to CCM
ram in allocations if the type is unspecified
