mpc83xx: cleanup System Part and Revision ID Register (SPRIDR) code
in the spirit of commit 1ced121600b2060ab2ff9f0fddd9421fd70a0dc6,
85xx's "Update SVR numbers to expand support", simplify SPRIDR processing
and processor ID display. Add REVID_{MAJ,MIN}OR macros to make
REVID dependent code simpler. Also added PARTID_NO_E and IS_E_PROCESSOR
convenience macros.
