ASoC: atmel: mchp-pdmc: add PDMC driver

The Pulse Density Microphone Controller (PDMC) interfaces up to 4 digital
microphones having Pulse Density Modulated (PDM) outputs. It generates a
single clock line and samples 1 or 2 data lines. The signal path includes
an audio grade programmable decimation filter and outputs 24-bit audio
words on the APB bus.
