What we did with PXA was to decide not to use definitions for the built-in
GPIOs - what's the point of:

#define GPIO0	0
#define GPIO1	1
#define GPIO2	2
...

It's a bit like:

#define NUMBER0	0
#define NUMBER1	1
etc.

Yes, there's a reason to if the number spaces are different, but for
the built-in GPIOs, they aren't.
