Pull power supply and reset updates from Sebastian Reichel:
 "battery/charger driver changes:
   - core:
      - provide function stubs if CONFIG_POWER_SUPPLY=n
      - reduce loglevel for probe defer info
   - surface:
      - new battery and charger drivers for Surface
   - bq27xxx:
      - add bq78z100 support
      - fix current_now/power_avg for newer chips
   - cw2015:
      - add CHARGE_NOW support
   - ab8500:
      - drop pdata support
   - convert most DT bindings to YAML
   - lots of minor fixes and cleanups

  reset drivers:
   - ltc2952-poweroff:
      - make trigger delay configurable from DT
   - minor fixes and cleanups"

+      This pin is not available on all devices however it should be used if

+      If this property is not specified, the input limit current is set
+      automatically using USB D+/D- signal based charger type detection.
