Linus Walleij f54005b508 mmc: pxa: Use GPIO descriptor for power 
After converting the PXA driver to use GPIO descriptors for
card detect and write protect it is relatively simple to
convert it to also use a descriptor for getting the optional
power control GPIO.

The polarity inversion flag can also go away from the platform
data since this is indicated in the GPIO machine descriptor
table.
