libata-pmp: update ata_eh_reset() for PMP
PMP always requires SRST to be enabled. Also, hardreset reports
classification code from the first device when PMP is attached, not
from the PMP. Update ata_eh_reset() such that followup softreset is
performed if the controller is PMP capable and the host link is being
reset.
