pci: add qemu gpex host bridge support.microvm
Find PCIe root using ACPI DSDT table.
Setup PCI bars.
initialize PCI devices.
Working:
- finds + drives xhci-pci / virtio-pci devices.
TODO / known issues:
- ioport setup is broken.
- bootorder needs fixing.
- 64bit mmio window not supported.
- irq routing not supported.
- pci config access in real mode is broken (not using mmconfig).
- this breaks pcibios support.
- which in turn breaks vgabios.
- fixable via temporary modeswitch to 32bit.
- which of course adds overhead.
Also:
- needed in the first place for microvm?
