arch, arm: Fix implicit-fallthrough GCC warnings
GCC 7 generates spurious fallthrough warnings in nested switch blocks
where the inner switch block return. There is already a GCC fix [1]
submitted for review but, until it is merged into GCC trunk, GEM5 will
not build with GCC 7 due to these fallthrough warnings. This patch
silences the spurious fallthrough warnings by appending a M5_UNREACHABLE
statement in the outer switch cases.
Note there is another GEM5 patch [2] to fix other fallthrough warnings.
