Scott Wood 06f60ae3e4 powerpc/mpc83xx: add support for new SPL
This adds arch support for PPC mpc83xx to boot "minimal" (4K) SPLs
using the new infrastructure.

Existing nand_spl targets are updated to deal with the name change
from nand_init.c to spl_minimal.c (as in theory this isn't limited
to NAND anymore).
