Subject: [PATCH] dio: Improve readability: rename dio_scodetophysaddr

Rename dio_scodetophysaddr to dio_scode_to_physaddr.
Also dio_scodetoipl -> dio_scode_to_ipl and dio_scode_to_name
-> dio_scode_to_name, though they're not implemented yet.
I've searched these names in the repo. There are only a few of references.
I think it's OK and worth renaming them for readability.
