Paul Geurts 6bea4f03c6 NFC: trf7970a: disable all regulators on removal 
During module probe, regulator 'vin' and 'vdd-io' are used and enabled,
but the vdd-io regulator overwrites the 'vin' regulator pointer. During
remove, only the vdd-io is disabled, as the vin regulator pointer is not
available anymore. When regulator_put() is called during resource
cleanup a kernel warning is given, as the regulator is still enabled.

Store the two regulators in separate pointers and disable both the
regulators on module remove.
