ALSA: ump: Add more attributes to UMP EP and FB info

Add a few more fields to snd_ump_endpoint_info and snd_ump_block_info
that are added in the new v1.1 spec.  Those are filled by the UMP Stream
messages.

The rawmidi protocol version is bumped to 2.0.4 to indicate those
updates.

Also, update the proc outputs to show the newly introduced fields.
