Add simple PMIO & PMIO2 read/write routines to CIMX wrapper

These are the PMIO & PMIO2 read & write routines from
src/southbridge/amd/sb800/sb800.c & sb800.h for use in the cimx
tree.  Currently most platforms using CIMX are calling WritePMIO()
directly from the src/vendorcode/amd/cimx/sbX00 directories
instead of using a wrapper function.
These functions only do byte reads & writes.
