ASoC: msm8960: Add support for AUX PCM Interface
Auxiliary PCM Interface is external PCM interface on msm that
can be used instead of internal codec as a way to connect an
external codec to the msm.
Enable support for AUX PCM. Current setting on PCM interface is,
2.048 MHz bit clock, mono stream, 8Khz sample rate, with MSM in
master mode. AUX PCM uses GPIO's to interface with external
codec device.
Adds platform data for cpu dai since cpu dai needs to know
which clock on MSM to use, clock rate to use and other
configuration parameters.
