 Raw Table Data: Length 912 (0x390)

Note that the contents of tests/data/q35/ERST.acpierst and
tests/data/microvm/ERST.pcie are the same except for differences
due to assigned base address.

Files tests/data/pc/DSDT.acpierst and tests/data/acpi/q35/DSDT.acpierst
are new files (and are included as a result of 'make check' process).
Rather than provide the entire content, I am providing the differences
between pc/DSDT and pc/DSDT.acpierst, and the difference between
q35/DSDT and q35/DSDT.acpierst, with an explanation to follow.

I have convinced myself of the changes we see in the DSDT tables.
On i440fx side, we are adding a non-hotpluggable pci device on slot 3.
So the changes we see are basically replacing an empty hotpluggable
slot on the pci root port with a non-hotplugggable device.
On q35, bsel on pcie root bus is not set (its not hotpluggable bus),
so the change basically adds the address enumeration for the device.

For both pc and q35, there is but a small difference between this
DSDT.acpierst and the corresponding DSDT. In both cases, the changes
occur under the hiearchy:

    Scope (\_SB)
    {
        Scope (PCI0)
        {

which leads me to believe that the change to the DSDT was needed
due to the introduction of the ERST PCI device.
