HW: Use unsigned indices in RegisterMMIO where applicable

base is an unsigned variable, so we can make things little more
consistent by making the loop index unsigned so we aren't doing bit
arithmetic with signed types.

MemoryInterface already does this, so we can leave it alone.

No behavioral changes, just a consistency thing.
