Subject: [PATCH v4 2/2] leds: qcom-lpg: Add PM660L configuration and compatible

Inherit PM660L PMIC LPG/triled block configuration from downstream
drivers and DT sources, consisting of a triled block with automatic
trickle charge control and source selection, three colored led channels
belonging to the synchronized triled block and one loose PWM channel.

Changes since v3:
- Rebased on -next;
- (series) dropped DTS patches that have been applied through the
  Qualcomm DTS tree, leaving only leds changes (driver and
  accompanying dt-bindings).
