The device argument passed to of_get_regulator_init_data is used to do some devres memory allocation. Currently the driver passes the MFD device pointer to this function, this could result in the init_data allocation being leaked if the regulator is unbound but the MFD isn't. Correct this issue by correctly passing the local platform device.
