hw/usb/vt82c686-uhci-pci: Use ISA instead of PCI interrupts

Browse Source 
This device is part of a superio/ISA bridge chip and IRQs from it are
routed to an ISA interrupt. Use via_isa_set_irq() function to implement
this in a vt82c686-uhci-pci specific irq handler.

This reverts commit 422a6e8075.
