ASoC: wm1250-ev1: Convert to GPIO descriptors 
This converts the WM1250-EV1 codec to use GPIO descriptors.
It turns out that the platform data was only used to pass some
global GPIO numbers from a board file, so we get rid of this
and also switch over the single in-tree user in the S3C
Cragganmore module for S3C 6410.

The driver obtains two GPIO lines named OSR and master and just
pull them low, we leave this behaviour as it was.
