MPP_F6281_MASK would be previously be returned when on mv88f6282,
which would disallow some valid MPP configurations.
Commit 830f8b91 (arm: plat-orion: fix printing of "MPP config
unavailable on this hardware") made this problem visible as an invalid
MPP configuration is now correctly detected and not applied.
