[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. Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
