Since there aren't any mmc aliases for rk3288 at the moment, I'll drop
this and send a patch adding them for the one board I have access to.

At some point the nonstandard mshc aliases should be removed, but it
may be best to keep them around for a while given that 5.17 will be the
first kernel that doesn't use these as a weird mechanism for per-port
settings.
