ASoC: codec: Convert to GPIO descriptors for

Merge series from Peng Fan <peng.fan@nxp.com>:

This patchset is a pick up of patch 1,2 from [1]. And I also collect
Linus's R-b for patch 2. After this patchset, there is only one user of
of_gpio.h left in sound driver(pxa2xx-ac97).

of_gpio.h is deprecated, update the driver to use GPIO descriptors.

Patch 1 is to drop legacy platform data which in-tree no users are using it
Patch 2 is to convert to GPIO descriptors

Checking the DTS that use the device, all are using GPIOD_ACTIVE_LOW
polarity for reset-gpios, so all should work as expected with this patch.
