ALSA: seq: Print UMP Endpoint and Block information in proc outputs
This patch enhances the /proc/asound/seq/clients output to show a few
more information about the assigned UMP Endpoint and Blocks.
The "Groups" are shown in 1-based group number to align with the
sequencer client name and port number.
