83xx/85xx/86xx: add more MxMR local bus definitions

This patch adds more macro definitions for the UPM Machine Mode Registers
They are copied from "include/mpc82xx.h" to simplify the merge of all 8xxx
common local bus definitions into include/asm-ppc/fsl_lbc.h. They are
required for my forthcoming FSL NAND UPM driver re-write and the support
for the TQM8548 module.

This patch is based on the following two patches from Anton Vorontsov:

http://www.mail-archive.com/u-boot-users@lists.sourceforge.net/msg06511.html
http://www.mail-archive.com/u-boot-users@lists.sourceforge.net/msg06587.html

I leave coding style violation fixes, code beautification and name
corrections to somebody else ;-(.
