There's more to it than that.
It's not an MFD driver because it's a card reader an nothing else.
MFDs cross subsystem boundaries, whereas this is just a card reader.
MFD isn't a dumping ground for devices which don't belong anywhere
else.

Without creating a new subsystem, I can't think of a better place for
it either.

This is odd.
You should move that file into include/.
