hw/usb/vt82c686-uhci-pci: Use ISA instead of PCI interrupts
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 422a6e8075752bc5342afd3eace23a4990dd7d98.
