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.

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.
And is explained in detail by Ani Sinha:
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.
