marlin/sailfish: set fixed brightness when entering LP mode
It's necessary to set maximum brightness while in low persistence mode
to maintain constant brightness regardless of the system brightness setting.
Note that since different devices require slightly different brightness settings
to achieve the same output intensity the value is specified in a new BoardConfig
variable.
