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 GPIO is optionally used to read the AC adapter status. This is a Host GPIO
+      that is configured as an input and connected to the ACOK pin on the bq24735.
+      Note: for backwards compatibility reasons, the GPIO must be active on AC adapter
+      absence despite ACOK being active (high) on AC adapter presence.

+      Used to control and set the charging current.
+      This value must be between 128mA and 8.128A with a 64mA step resolution.
+      The POR value is 0x0000h. This number is in mA (e.g. 8192).
