fbd-dev-leds: Probe QCOM HW LED types

Browse Source 
Try first the QCOM hardware LED types which require the most features of
LED drivers. Try until we have a single color GPIO LED which is the
minimal LED driver support we require. If the LED does not meet that
expectation either, we ignore the LED.
