ASoC: codecs: wcd: add common helper for wcd codecs

All the Qualcomm WCD codecs have most of its code duplicated across all
these 3/4 drivers. This is an attempt to remove those duplicate
parts by adding a common helper library for these codecs.

To start with move all the micbias parsing and voltage settings these
are identical in WCD934x, WCD937x, WCD938x and WCD939x codec driver.
