  [chibios] add ppm driver

- Right now ChibiOs supports only first two channels on each timer for time 
capture
- required modification of ChibiOS (define for Channel 3 for Timers), will push 
it soon
- uses callbacks for timer updates and event listeners/broadcasting for 
processing the frame (see the code)
- tested with Turnugy 9xr

Note that once these drivers are finished, I will update the boad config files 
accordingly. It would just be messy to do it for each driver separately.
The same for main_chibios.c and the threads/events.

closes #581
