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".
