powerpc/e6500: hardware tablewalk support
Preliminary support for e6500 hardware tablewalk. This is for simulator
(and rev2) only. On rev1 hardware, be sure to set
CONFIG_PPC_FSL_BUGGY_HW_TABLEWALK.
Locking is introduced to make TLB misses threadsafe. TODO: add locking to
the non-tablewalk miss handlers, which was the main reason for making the
locking conditional.
