fbd-dev-led-qcom: Support QCOM LPG LED single color

Browse Source 
QCOM LPG LEDs expose a hw_pattern sysfs entry which accepts a limited
set of patterns but allows to use dedicated hardware for blinking the
LED. This way, battery life can be improved and the LED still blinks,
even if the device is suspended.
