ASoC: wm8996: Convert to GPIO descriptors

This converts the WM8996 codec to use GPIO descriptors, an a similar
way to WM5100.

The driver is instantiating a GPIO chip named wm8996, and we get
rid of the base address for the GPIO chip from the platform data and
just use dynamic numbering. Move base and ngpio into the static
gpio_chip template.

Fix up the only in-tree user which is the Cragganmore 6410 module.

ASoC: Rename WM8915 to WM8996

For marketing reasons the part will be called WM8996. In order to avoid
user confusion rename the driver to reflect this.
