Add the tlv320adcx140 codec driver family.

The TLV320ADCx140 is a Burr-Brown™ highperformance, audio analog-to-digital
converter (ADC) that supports simultaneous sampling of up to four analog
channels or eight digital channels for the pulse density modulation (PDM)
microphone input. The device supports line and microphone inputs, and
allows for both single-ended and differential input configurations.
