Power: bq25896 and bq27220 drivers, portable power api. (#224)

* Power: add portability layer, port to F3.
* F3: bq25896 driver stab
* GUI: new primary and secondary fonts
* F3: bq25896 register map, basic functions
* F3: move bq27220 command descritpion to separate file. Code format.
* Power: OTG enable/disable
* Power: choose more correct profile
* F3: pet bq25896 watchdog sometimes
