Since this is a MemoryListener operation, it only makes sense
on an AddressSpace granularity.

"Readable" is a very unfortunate name for this flag because even a
rom_device region will always be readable from the guest POV. What
differs is the mapping, just like the comments had to explain already.
Also, readable could currently be understood as being a generic region
flag, but it only applies to rom_device regions.
So rename the flag and the function to modify it after the original term
"ROMD" which could also be interpreted as "ROM direct", i.e. ROM mode
with direct access. In any case, the scope of the flag is clearer now.

memory_region_find() is similar to registering a MemoryListener and
checking for the MemoryRegionSections that come from a particular
region. There is no reason for this to be limited to a root memory
region.
