powerpc/mm: Tweak PTE bit combination definitions
This patch tweaks the way some PTE bit combinations are defined, in
such a way that the 32 and 64-bit variant become almost identical
and that will make it easier to bring in a new common pte-* file
for the new variant of the Book3-E support.
The combination of bits defining access to kernel pages are now
clearly separated from the combination used by userspace and the
core VM. The resulting generated code should remain identical
unless I made a mistake.
Note: While at it, I removed a non-sensical statement related to
CONFIG_KGDB in ppc_mmu_32.c which could cause kernel mappings to be
user accessible when that option is enabled. Probably something
that bitrot.
