Igor Mammedov 47a373faa6 acpi: pc/q35: drop ad-hoc PCI-ISA bridge AML routines and let bus ennumeration generate AML
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.
