Disable icache emulation for Monster House

This game has stale icache values in the logs during certain
loadscreens, and after disabling them I was able to play through the
entire game, with one crash that may have been related to savestates and
memory cards since during that loadscreen it said the memory card did
not match.

This does cause invalid reads to be spit out during parts of the game,
but you can safely skip them.  Enabling MMU seems to surpress the
invalid reads without side-effects, but the aforementioned
memcard/savestate crash was with MMU on.
