Add the pxa3xx architecture, for pxa300, pxa310 and pxa320 SoCs.
This includes :
- the registers
- the cpu type
- the reset source handling
- a minimal set of clocks
- pin control definitions
In this last case, the big mfp-pxaxxx.h files were dropped, forcing
board developers to use MFP_LPM_* macros cunningly.
