This adds a driver for the TI PCM9211 digital audio interfaces transceiver. The driver currently only handles the receiver aspect of the chip and supports only control of the primary I2S (MAIN) output port. Support for AUX output is trivial to add, but wasn't done due to missing hardware for testing. The same goes for the transmitter functionality. The driver uses some extra device-tree fields to allow configuration of pin functions directly out of this driver.

In above block; reset should be int0, three lines affected.
