ASoC: cs4234: Add support for Cirrus Logic CS4234 codec
The CS4234 is a highly versatile CODEC that combines 4 channels of
high performance analog to digital conversion, 4 channels of high
performance digital to analog conversion for audio, and 1 channel of
digital to analog conversion to provide a nondelayed audio reference
signal to an external Class H tracking power supply.

DAC5 is only supported as a 5th audio channel. Tracking Power Supply
mode is not currently supported by the driver.

In DSP_A mode the slots for DAC1-4 and optionally DAC5 can be set.
The codec always claims 4 slots for DAC1-4 and these must be in the
same nibble of the mask. The codec has a fixed mapping for ADC slots.

In I2S/LJ modes the codec has a fixed mapping for DAC1-4 and ADC1-4.
DAC5 is not available in these modes.

The MCLK source must be preset to a valid frequency before probe()
because it must be running all the time the codec is out of reset.

The VA_SEL bit will be set automatically to 3.3v or 5v during probe()
based on the reported voltage of the regulator supplying VA.
