power supply and reset changes for the 6.9 series 

* new features
   - axp20x_usb_power: report USB type
 * cleanups
   - convert lots of drivers to use devm_power_supply_register()
   - convert lots of reset drivers to use devm_register_sys_off_handler()
   - constify device_type and power_supply_class
   - axp20x_usb_power: use correct property to report input current limit
   - mm8013: correct handling of "not charging" status register
   - core: fix charge_behaviour formatting
   - minor fixes cleanups
