arm: Don't force the ArmISA::TLB in vtophys.cc.

The only reason the TLB pointer is being cast to an ArmISA::TLB is so
that it can call a version of translateFunctional which takes more
arguments, when the standard version of translateFunctional just calls
that underlying function with the same arguments.
