This adds some missing hooks for ufs commands, including request, query, uic, task manager commands, and interrupt events for vendor. Those can be used for vendor module to understand command history. Bug: 172305874 Bug: 176940922 Signed-off-by: Jaegeuk Kim <jaegeuk@google.com> Change-Id: Ie447860290f4fbc1e03ad8ae5f50bd02121756cb
