backlight evolution: API between Condat driver and MFW
With this change, the API between the Condat backlight driver
and its user in MFW now carries more abstract backlight state codes
(fully off, fully on, in call, charging boot mode) instead of
0-255 levels. This change is needed in order to more properly support
different hardware targets with different capabilities and approaches
in terms of backlight handling.
