Revert "Rework MMU trait to allow for full control of MMU issued memory cycles"
...
This commit breaks accesses to the MMU IO space because since the
MMU card is borrowed during accesses to memory, when it calls
into the backplane to do the physical access, the
backplane will attemp to borrow the MMU card again,
causing a panic
