Catch up MIDI 2.0 updates for UMP 1.1 [LWN.net]

Hi,

as the updated MIDI 2.0 spec has been published freshly [*], this is a
catch up to add the support for new specs, especially UMP v1.1
features, on Linux kernel.

The new UMP v1.1 introduced the concept of Function Blocks (FB), which
is a kind of superset of USB MIDI 2.0 Group Terminal Blocks (GTB).
The patch set adds the support for FB as the primary information
source while keeping the parse of GTB as fallback.  Also UMP v1.1
supports the groupless messages, the protocol switch, static FBs, and
other new fundamental features, and those are supported as well.
