tests/acpi: update expected DSDT blob for aarch64 and microvm
After PCI link devices are moved out of the scope of PCI root complex,
the DSDT files of machines which use GPEX, will change. So, update the
expected AML files with these changes for these machines.
Mainly, there are 2 changes.
1) Since the link devices are created now directly under _SB for all PCI
root bridges in the system, they should have unique names. So, instead
of GSIx, named those devices as LXXY where L means link, XX will have
PCI bus number and Y will have the INTx number (ex: L000 or L001). The
_PRT entries will also be updated to reflect this name change.
2) PCI link devices are moved from the scope of each PCI root bridge to
directly under _SB.
Below is the sample iASL difference for one such link device.
Scope (\_SB)
