two reasons:
1. GPIO namings and their mode definitions are conceptually not part
   of the PXA register definitions

2. this is actually a temporary move in the transition of PXA2xx to
   use MFP-alike APIs (as what PXA3xx is now doing), so that legacy
   code will still work and new code can be added in step by step

This patch adds a PXA2xx specific header file to control chip setup.
Without, the PCM027 BSP can't be built.

This patch adds main support for the generic phyCORE-PXA270 CPU module
(aka PCM-027). Its as generic as possible to support any kind of baseboard.

Note: Neither the CPU module nor the pcm027.c implementation can work without
a baseboard support. Baseboard support can be added by the PCM-990 or any
custom variant.

V2:
 After comments by Eric Miao:
  - Currently unsupported devices moved into separate patch
  - direct call of baseboard initialisation

V3:
 After comments by Russell King
  - sort include files
  - setting RTC bit for power control removed
 - style problems fixed (discovered by checkpatch.pl)
