This converts the WM5100 codec to use GPIO descriptors, a pretty
straight-forward conversion with the following peculiarities:

- The driver is instantiating a GPIO chip named wm5100, and the
  headphone polarity detection GPIO is lifted from there. We add
  this to the GPIO descriptor table as well, and we can then get
  rid of also the base address for the GPIO chip from the
  platform data and just use dynamic numbering.

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