ARM: pxa: Add gpio descriptor lookup tables for MMC CD/WP
This adds GPIO descriptor look-up tables for a whole bunch of PXA boards with MMC card detect (CD) and write protect (WP) GPIO lines, so we can move away from the hard-coded GPIO numberspace. In some cases the platforms were compulsively including the <linux/gpio.h> header even if they weren't actually using it, and in these cases I simply replaced that inclusion with the more appropriate <linux/gpio/machine.h> which is what board files should be including most of the time.
