dt-bindings: leds: qcom-lpg: Explain standalone PWM usage 



LPG channels can be used for only outputting PWM signals by routing to
PMIC GPIOs without enabling TRILED. Explain this usage in the description
for better clarity.

  The Qualcomm Light Pulse Generator consists of three different hardware blocks;

  a ramp generator with lookup table (LUT), the light pulse generator and a three

  channel current sink. These blocks are found in a wide range of Qualcomm PMICs.

  The light pulse generator (LPG) can also be used independently to output PWM

  signal for standard PWM applications. In this scenario, the LPG output should

  be routed to a specific PMIC GPIO by setting the GPIO pin mux to the special

  functions indicated in the datasheet, the TRILED driver for the channel will

  not be enabled in this configuration.
