PATCH v2 1/1 ARM: pxa: dts: add pin definitions for extended GPIOs

The PXA3xx series features some extended GPIO banks which are named GPIO0_2, GPIO1_2 etc. The PXA300, PXA310 and PXA320 have different numbers of such pins, and they also have variant-specific register offsets.

Applied to pxa/dt, thanks.

Cheers.
