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: default debug checks off
...
these can be enabled as needed for board bringup, but are too
expensive for general use

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
