032a443be6 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 422a6e8075.

422a6e8075 hw/usb/vt82c686-uhci-pci: Use PCI IRQ routing
According to the PCI specification, PCI_INTERRUPT_LINE shall have no
effect on hardware operations. Now that the VIA south bridges implement
the internal PCI interrupt router let's be more conformant to the PCI
specification.

4f3b0a4d75 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 set by the Interrupt Line PCI config
register. Implement this in a vt82c686-uhci-pci specific irq handler
Using via_isa_set_irq().

ece29df33b usb/uhci: Disallow user creating a vt82c686-uhci-pci device
Because this device only works as part of VIA superio chips set user
creatable to false. Since the class init method is common for UHCI
variants introduce a flag in UHCIInfo for this.

Extract the VT82C686 PCI UHCI function into a new unit so
it is only build when the VT82C686 south bridge is selected.
