arch, arm: Update miscRegs in getTE

Normally, a translation will start via translateTiming/functional
which will check if the miscRegs have been updated and if so,
will update the TLB state accordingly.  However, in a 2 stage
system, if there is a hit in stage 1, the resulting IPA will be
sent to the S2-TLB for translation via a getTE() function call
(via the stage2_lookup object).  This will cause the state of the
S2-TLB to be out of sync.
