ASoC: codecs: add new pm4125 audio codec driver
The audio codec is found in Qualcomm PM2250/PM4125 PMICs and is used on platforms like Qualcomm QCM2290. It has soundwire interface and corresponding RX and TX slave devices. It has only two input channels: HPH left and right. The line output (LO) is linked to HPHL so the hardware has some limitations regarding concurrent playback via HPH and LO for instance. The codec driver also uses WCD MBCH framework. The MBHC functionality is implemented in a minimalistic way to enable IRQs and avoid different issues with IRQs.
