ASoC: codec: Remove ak4641/pxa2xx-ac97 and convert to

Merge series from "Peng Fan (OSS)" <peng.fan@oss.nxp.com>:

The main goal is to convert drivers to use GPIO descriptors. While reading
the code, I think it is time to remove ak4641 and pxa2xx-ac97 driver,
more info could be found in commit log of each patch.
Then only need to convert sound/arm/pxa2xx-ac97-lib.c to use GPIO
descriptors. Not have hardware to test the pxa2xx ac97.
