Simplify things by making the PXA MCI driver just use
slot GPIO with descriptors instead of passing around the global
GPIO numbers that we want to get rid of.
This involves augmenting more or less every PXA boardfile,
associating each card detect or write protect line with the
right GPIO chip or GPIO expander.
As we are no longer checking for global GPIO numbers we avoid
having to fill them in at all in the platform data including
the kludge of setting the GPIO to -1 when we don't have either
signal. We just look for the slot GPIO descriptor for CD and
WP and if we find it we use it.
We take care of correctly specifying the edge sensitivity of
the GPIO lines (active low or active high) so we can later
on use this flag even though the MMC slot GPIO code uses the
*raw accessors and rely on the caps2 flags
MMC_CAP2_CD_ACTIVE_HIGH and MMC_CAP2_RO_ACTIVE_HIGH for polarity
inversion semantics as of now.

Thanks for doing this!
However, I'm planning to remove that file entirely very soon, and
replace it with a dtb version. In order to avoid conflicts in the merge
window - could you respin and leave the file untouched?
Thanks,
Daniel
