NFC: trf7970a: trf7970a_init() turns off the RF transmitter
When trf7970a_init() initializes the trf7970a it implicitly turns off the RF transmitter. Track this by clearing the TRF7970A_CHIP_STATUS_RF_ON bit in the cached trf->chip_status_ctrl. Signed-off-by: Mark A. Greer <mgreer@animalcreek.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
