[FL-1506, FL-2197] Power, USB, LED driver improvements (#966)

Browse Source 
* Power, USB, LED driver improvements
* u2f hid descriptor fix
* variable_item_list: value alignment fix
* InputTypeRepeat handling in menu/submenu/var_item_list
* lp5562: fix bugs on 400khz i2c
* Scripts: lint in parallel.
* FuriHal: rename some USB structure to match naming convention. Drivers: update magic values in LP5562.
