Pull VFIO updates from Alex Williamson:

 - Relax IGD support code to match display class device rather than
   specifically requiring a VGA device (Tomita Moeko)

 - Accelerate DMA mapping of device MMIO by iterating at PMD and PUD
   levels to take advantage of huge pfnmap support added in v6.12
   (Alex Williamson)

 - Extend virtio vfio-pci variant driver to include migration support
   for block devices where enabled by the PF (Yishai Hadas)

 - Virtualize INTx PIN register for devices where the platform does not
   route legacy PCI interrupts for the device and the interrupt is
   reported as IRQ_NOTCONNECTED (Alex Williamson)
