Will Deacon e1a5848e33 ARM: 7924/1: mm: don't bother with reserved ttbr0 when running with LPAE
With the new ASID allocation algorithm, active ASIDs at the time of a
rollover event will be marked as reserved, so active mm_structs can
continue to operate with the same ASID as before. This in turn means
that we don't need to worry about allocating a new ASID to an mm that
is currently active (installed in TTBR0).

Since updating the pgd and ASID is atomic on LPAE systems (by virtue of
the two being fields in the same hardware register), we can dispose of
the reserved TTBR0 and rely on whatever tables we currently have live.
