86xx: Cleanup MP support
* Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx
* Introduce determine_mp_bootpg() helper. We'll 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.
* Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to
allow cmd_mp.c to build and work. In the future we should look at
implementing all these functions. This could be common w/85xx if we
use spin tables on 86xx.
