Fixes for functional path.

If the cpu needs to update any state when it gets a functional write (LSQ??)
then that code needs to be written.

src/cpu/o3/fetch_impl.hh:
src/cpu/o3/lsq_impl.hh:
src/cpu/ozone/front_end_impl.hh:
src/cpu/ozone/lw_lsq_impl.hh:
src/cpu/simple/atomic.cc:
src/cpu/simple/timing.cc:
    CPU's can recieve functional accesses, they need to determine if they need to do anything with them.
src/mem/bus.cc:
src/mem/bus.hh:
    Make the fuctional path do the correct tye of snoop
