powerpc/mm: Add support for handling > 512TB address in SLB miss
For addresses above 512TB we allocate additional mmu contexts. To make
it all easy, addresses above 512TB are handled with IR/DR=1 and with
stack frame setup.
The mmu_context_t is also updated to track the new extended_ids. To
support upto 4PB we need a total 8 contexts.

[mpe: Minor formatting tweaks and comment wording, switch BUG to WARN
in get_ea_context().]
