85xx: Introduce determine_mp_bootpg() helper.
Match determine_mp_bootpg() that was added for 86xx. We need this to
address a bug introduced in v2009.03 with 86xx MP booting. We have to
make sure to reserve the region of memory used for the MP bootpg() so
other u-boot code doesn't use it.
Also added a comment about how cpu_reset() is dealing w/an errata on
early 85xx MP HW.
