power: supply: generic-adc-battery: Use GPIO descriptors
This driver uses platform data to pass GPIO lines using the deprecated global GPIO numbers. There are no in-tree users of this platform data. Any out-of-tree or coming users of this driver can easily be migrated to use machine descriptor tables as described in Documentation/driver-api/gpio/board.rst section "platform data".
