Add the ability to configure the MFP1->MFP5 registers
as GPIOs. In addition adding ALSA controls to get and set
the GPIO state.
Per the data sheet each MFP can be configured as a GPIO
input only, output only or either an input or output.

Add support for the tlv320aic32x6 family of devices.
These devices share the same register set as the tlv320aic32x4
and this driver can be re-used.
TLV320aic32x6 data sheets are here:
tlv320aic3256 - http://www.ti.com/lit/gpn/tlv320aic3256

Add support for a master clock passed through DT. The master clock of
the codec is only active when the codec is in use.

Add DT support for this codec. The bindings differ a bit from the aic3x
codec bindings, so I created a new binding documentation.
