ahci-vt8251
* requires hardreset after PHY status change
* doesn't clear BSY on signature FIS after hardreset
* needs SError cleared for the port to operate after hardreset
This patch implements ahci_vt8251_hardreset() and sets
ATA_FLAG_HRST_TO_RESUME to handle the above behaviors. This fixes EH
including hotplug on vt8251.
