powerpc: rename immap_86xx.h to fsl_guts.h, and add 85xx support

The immap_86xx.h header file only defines one data structure: the "global
utilities" register set found on Freescale PowerPC SOCs.  Rename this file
to fsl_guts.h to reflect its true purpose, and extend it to cover the "GUTS"
register set on 85xx chips.
