memory: tune mtree_print_mr() to dump mr type

Browse Source 
We were dumping RW bits for each memory region, that might be confusing.
It'll make more sense to dump the memory region type directly rather
than the RW bits since that's how the bits are derived.

Meanwhile, with some slight cleanup in the function.
