ALSA: ump: Add info flag bit for static blocks

Browse source

UMP v1.1 spec allows to inform whether the function blocks are static
and not dynamically updated.  Add a new flag bit to
snd_ump_endpoint_info to reflect that attribute, too.

The flag is set when a USB MIDI device is still in the old MIDI 2.0
without UMP 1.1 support.  Then the driver falls back to GTBs, and they
are supposed to be static-only.
