Rework BookE pmap towards multi-core support.

o Eliminate tlb0[] (a s/w copy of TLB0)
  - The table contents cannot be maintained reliably in multiple MMU
    environments, where asynchronous events (invalidations from other cores)
    can change our local TLB0 contents underneath.
  - Simplify and optimize TLB flushing: system wide invalidations are
    performed using tlbivax instruction (propagates to other cores), for
    local MMU invalidations a new optimized routine (assembly) is introduced.

o Improve and simplify TID allocation and management.
  - Let each core keep track of its TID allocations.
  - Simplify TID recycling, eliminate dead code.
  - Drop the now unused powerpc/booke/support.S file.

o Improve page tables management logic.

o Simplify TLB1 manipulation routines.

o Other improvements and polishing.
