QCOM LPG LEDs can also operate in a multicolor fashion.
Re-use the probing sequence of multicolor LEDs and the hw_pattern
configuration of single color QCOM LPG LEDs.
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.
