s390/dasd: add autoquiesce feature
Add the internal logic to check for autoquiesce triggers and handle
them.
Quiesce and resume are functions that tell Linux to stop/resume
issuing I/Os to a specific DASD.
The DASD driver allows a manual quiesce/resume via ioctl.
Autoquiesce will define an amount of triggers that will lead to
an automatic quiesce if a certain event occurs.
There is no automatic resume.
All events will be reported via DASD Extended Error Reporting (EER)
if configured.
