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.
