Backlight support. TOUCH events feed backlight_keepalive(); After a timeout, we fade the backlight to 0 using timers. When the backlight is not active, TOUCH events are not passed to widgets, but the backlight is re-enabled; Add some flags to mos.yml to drive timeout and PWM pin for the backlight on Featherwing
