soc: qcom: eud: Fix the power supply information

Browse source 
The EUD driver operates on the power-supply property,
POWER_SUPPLY_PROP_INPUT_CURRENT_LIMIT, under the power-supply "battery".
This is incorrect as POWER_SUPPLY_PROP_INPUT_CURRENT_LIMIT is a part of
"usb" power-supply and not "battery". Hence, configure the driver with
the correct power-supply (and alter the names of corresponding
variables and functions).

Also, drop the reference to the power-supply from the platform driver's
.remove callback.
