Convert the Wolfson WM9713 to regmap API. This will leverage all the
regmap functions (debug, registers update, etc ...).
As a bonus, this will pave the path to gpio chip introduction, and
devicetree support. This was tested on the mioa701 board, pxa27x based,
in PCM playback, and through suspend/resume.

Since v1: fix suspend/resume (that specific part is not tested yet)
Since v2: split out the snd_soc_*() from regmap support
Since v3: remove suspend/resume regmap cache operations, rely on
regmap volatile registers
