sim: Move the BaseTLB to src/arch/generic/

The TLB-related code is generally architecture dependent and should
live in the arch directory to signify that.

--HG--
rename : src/sim/BaseTLB.py => src/arch/generic/BaseTLB.py
rename : src/sim/tlb.cc => src/arch/generic/tlb.cc
rename : src/sim/tlb.hh => src/arch/generic/tlb.hh
