scsi: ufs: Add history of fatal events
Currently only "interrupt-based" errors have their own history, however
there are some "non-interrupt-based" errors or events which need history
to improve debugging or help know the health status of UFS devices.
Example of fatal errors:
- Link startup error
- Suspend error
- Resume error
Example of abnormal events:
- Task or request abort
- Device reset (now equals to Logical Unit Reset)
- Host reset
This patch tries to track above errors and events by existed UFS error
history mechanism.
