ASoC: samsung: speyside: Convert to GPIO descriptor

The Speyside ASoC uses a single GPIO from the WM8996
that we can provide from the local offset on that chip
rather than from the global GPIO numberspace as is being
done currently.

The offset 2 was done by calculating the base offset
for the CODEC (i.e. wm8996) GPIOs to 212, by reading
arch/arm/mach-s3c/gpio-samsung-s3c64xx.h and
arch/arm/mach-s3c/crag6410.h and adding up all the
offsets that were occasionally adding a +1 blank GPIO
between each GPIO provider.
