[PATCH] libata-eh: implement new EH
Implement new EH. The exported interface is ata_do_eh() which is to
be called from ->error_handler and performs the following steps to
recover the failed port.
ata_eh_autopsy() : analyze SError/TF, determine the cause of failure
and required recovery actions and record it in
ap->eh_context
ata_eh_report() : report the failure to user
ata_eh_recover() : perform recovery actions described in ap->eh_context
ata_eh_finish() : finish failed qcs
LLDDs can customize error handling by modifying eh_context before
calling ata_do_eh() or, if necessary, doing so inbetween each major
steps by calling each step explicitly.
