Many of the Gateworks Ventana boards use a PLX PEX860X PCIe Switch
and utilize its GPIO outputs as PERST# for downstream ports. This
patch configures them appropriately during enumeration.
Additionally many of the Ventana boards use CKO1 as the clock input for
an analog audio codec which is setup here.
