Vitaly Bordug f2a0bd3753 [POWERPC] 8xx: powerpc port of core CPM PIC
This covers common CPM access functions, CPM interrupt controller code,
micropatch and a few compatibility things to kee the same driver base
working with arch/ppc. This version is refined with all the comments
(mostly PIC-related) addressed.
