ahci: avoton port-disable reset-quirk

[ Upstream commit dbfe8ef5599a5370abc441fcdbb382b656563eb4 ]

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.
