power: supply: ug3105_battery: Switch to power_supply_batinfo_ocv2cap()

Replace the hardcoded ocv -> capacity table and the ug3105_get_capacity()
helper with using the generic power_supply_batinfo_ocv2cap() function.

Note this relies on the battery fwnode providing at least 1
"ocv-capacity-table", if that is missing probe() will now fail with EINVAL.
