PPC's 'opal' match pattern also matches block/sed-opal.c, where it looks

We thought of it first.

Can't you just rename your driver, Opal Storage Specification, so "oss",
that should be pretty unique?

I don't like this version, but I'll merge the one from Stewart which
drops the pattern and adds the paths for the existing drivers.
