wcd937x codec fixes

Merge series from Alexey Klimov <alexey.klimov@linaro.org>:

This sent as RFC because of the following:

- regarding the LO switch patch. I've got info about that from two persons
independently hence not sure what tags to put there and who should be
the author. Please let me know if that needs to be corrected.

- the wcd937x pdm watchdog is a problem for audio playback and needs to be
fixed. The minimal fix would be to at least increase timeout value but
it will still trigger in case of plenty of dbg messages or other
delay-generating things. Unfortunately, I can't test HPHL/R outputs hence
the patch is only for AUX. The other options would be introducing
module parameter for debugging and using HOLD_OFF bit for that or
adding Kconfig option.
