PCI-ISA bridges that are built in PIIX/Q35 are building its own AML using AcpiDevAmlIf interface. Now build_append_pci_bus_devices() gained AcpiDevAmlIf interface support to get AML of devices atached to PCI slots. So drop ad-hoc build_q35_isa_bridge()/build_piix4_isa_bridge() and let PCI bus enumeration to include PCI-ISA bridge AML when it's enumerated by build_append_pci_bus_devices(). AML change is mostly contextual, which moves whole ISA hierarchy directly under PCI host bridge instead of it being described as separate \SB.PCI0.ISA block. Note: If bus/slot that hosts ISA bridge has BSEL set, it will gain new ASUN and _DMS entries (i.e. acpi-index support, but it should not cause any functional change and that is fine from PCI Firmware spec point of view), potentially it's possible to suppress that by adding a flag to PCIDevice but I don't see a reason to do that yet, I'd rather treat bridge just as any other PCI device if it's possible.
