leds: Add driver for Qualcomm LPG

The Light Pulse Generator (LPG) is a PWM-block found in a wide range of PMICs from Qualcomm. It can operate on fixed parameters or based on a lookup-table, altering the duty cycle over time - which provides the means for e.g. hardware assisted transitions of LED brightness.
