mmu-hash32: Clean up BAT matching logic
The code to search for a matching BAT for a virtual address is somewhat longwinded and awkward. In particular, it relies on seperate size and validity information being returned from the hash32_bat_size() function (and 601 specific variant). We simplify this by having hash32_bat_size() return instead a mask of the virtual address bits to match, and 0 for invalid (since a BAT can never match the entire address space).
