regulator: gpio: Get enable GPIO using GPIO descriptor

Browse Source 
We augment the GPIO regulator to get the *enable* regulator
GPIO line (not the other lines) using a descriptor rather than
a global number.

We then pass this into the regulator core which has been
prepared to hande enable descriptors in a separate patch.

Switch over the two boardfiles using this facility and clean
up so we only pass descriptors around.
