HID: input: Convert battery code to devm_*

Browse source

Convert the HID battery code to use devm_* managed resource APIs for
the power_supply_desc allocation, battery name string, and power supply
registration.

The error path uses devm_kfree() to clean up allocated memory if
devm_power_supply_register() fails, preventing memory waste on repeated
setup attempts. The hidinput_cleanup_battery() function is removed as
devm handles cleanup automatically.
