seq: Add snd_seq_{get|set}_ump_is_midi1() API functions

Browse source 
Implement the API function calls corresponding to the new sequencer
port flag bit that has been added recently to the kernel.
A UMP MIDI 2.0 device allow to have an optional MIDI 1.0 port while
speaking in MIDI 2.0 protocol for other UMP Groups.  The new seq port
flag indicates that.

This is rather a minor difference, and since ALSA sequencer core
covers the all conversions, usually you don't have to worry about it
at all.
