ahci: avoton port-disable reset-quirk
commit dbfe8ef5599a5370abc441fcdbb382b656563eb4 upstream.
Avoton AHCI occasionally sees drive probe timeouts at driver load time.
When this happens SCR_STATUS indicates device detected, but no D2H FIS
reception. Reset the internal link state machines by bouncing
port-enable in the PCS register when this occurs.

- use ahci_start_engine() instead of hpriv->start_engine()]
