dt-bindings: leds: Add LED1202 LED Controller 

The LED1202 is a 12-channel low quiescent current LED driver with:
  * Supply range from 2.6 V to 5 V
  * 20 mA current capability per channel
  * 1.8 V compatible I2C control interface
  * 8-bit analog dimming individual control
  * 12-bit local PWM resolution
  * 8 programmable patterns

If the led node is present in the controller then the channel is
set to active.

description: |
The LED1202 is a 12-channel low quiescent current LED controller
programmable via I2C; The output current can be adjusted separately
for each channel by 8-bit analog and 12-bit digital dimming control.
