powerpc: Move duplicated BAT defines to mmu.h
The BAT fields are architected; there's no need for these to be in
cpu-specific files. Drop the duplication and move these to
include/asm-ppc/mmu.h. Also, remove the BL_xxx defines that were only
used by the alaska board, and switch to using the BATU_BL_xxx defines
used by all the other boards. The BL_ defines previously in use
had to be shifted into the proper position for use, which was inefficient.
