move to single OSD font on some boards
this saves about 12k on these boards. They were also extremely close
to overflowing flash, under 2k on some
Now that we support having an OSD font on the microSD card (where
available) we can reduce built in fonts without a large functionality
impact
This also disables some less used features on these boards:
- generator support
- object avoidance path planning
- precision landing
This will give us some breathing room on these boards
with the new ChibiOS revision we were configuring for newer revisions
of the H7, which meant that we changed the ADC config. This broke ADC
readings on revX and revY H7 MCUs.
This PR fixes it in two ways:
1) change ChibiOS config to assume XY config chips
2) use 16 bit ADC for H7, which means the chip rev doesn't matter,
and also gives us 16x the resolution for ADC readinga, so we can
read smaller voltage and current values
this enables the parameter backup/restore on those boards, as well as
more waypoints
This is in response to a report that CUAVv5 boards can suffer from the
parameter reset issue
this takes better advantage of the new UART code. Log download over
USB gets to 730 kbyte/s. For comparison, with the 4.0 code on the same
H7 we get about 300 kbyte/s
this gains about 20k of RAM, and has almost no impact on log download
speed at 921600 on a F427. The improved threading means we can afford
to have smaller buffers

move uart DMA completion to event model
process dshot locks in strick reverse order when unlocking
convert Shared_DMA to use mutexes

do blocking dshot DMA transactions
trim stack sizes
cancel dma transactions on dshot when timeout occurs
support contention stats on blocking locking

invalidate DMA bounce buffer correctly
separate UART initialisation into two halves
cleanup UART transaction timeouts
add @SYS/uarts.txt
