ASoC: ti: Convert N810 ASoC to GPIO descriptors
The N810 uses GPIO descriptors pretty much exclusively, but not
for ASoC, so let's fix it. Register the pins in a descriptor table
in the machine since the ASoC device is not using device tree.
Use static locals for the GPIO descriptors because I'm not able
to experient with better state storage on any real hardware. Others
using the N810 can come afterwards and improve this.
