ALSA: seq: Print MIDI 1.0 specific port in proc output

When a sequencer port assigned to a UMP Group that is specific to MIDI
1.0 among MIDI 2.0 client, mark it explicitly in the proc output, so
that user can see it easily.  This is an exceptional case where the
message isn't converted to MIDI 1.0 even if the client is running in
MIDI 2.0 mode.
