USB: Add VIA quirk fixup for VT8235 usb2

Patch to add VIA PCI quirk for Enhanced/Extended USB on VT8235
southbridge. It is needed in order to use EHCI/USB 2.0 with ACPI.
Without it IRQs are not routed correctly, you get an "Unlink after
no-IRQ?" error and the device is unusable.

I belive this could also be a fix for Bugzilla Bug 5835.
