ALSA: seq: ump: Handle FB info update
This patch implements the handling of the dynamic update of FB info. When the FB info update is received after the initial parsing, it means the dynamic FB info update. We compare the result, and if the actual update is detected, it's notified via a new ops, notify_fb_change, to the sequencer client, and the corresponding sequencer ports are updated accordingly.
