Igor Mammedov fd4f2ae8ec tests: acpi: update expected DSDT after ISA bridge is moved directly under PCI host bridge
example of the change for PC machine with hotplug disabled on root buss (no BSEL case):

 -        Field (PCI0.ISA.P40C, ByteAcc, NoLock, Preserve)
 +        Field (S08.P40C, ByteAcc, NoLock, Preserve)

 ===
 -    Scope (_SB.PCI0)
 -    {
 -        Device (ISA)
 -        {
 -            Name (_ADR, 0x00010000)  // _ADR: Address
 -            OperationRegion (P40C, PCI_Config, 0x60, 0x04)
 ...
 -        }
 -    }
 -
      Scope (_SB)
 ===
 +            Device (S08)
 +            {
 +                Name (_ADR, 0x00010000)  // _ADR: Address
 +                OperationRegion (P40C, PCI_Config, 0x60, 0x04)
 ...
 +            }
 +
              Device (S10)
              {
                  Name (_ADR, 0x00020000)  // _ADR: Address

with hotplug enabled on root bus (i.e. bus has BSEL configured),
a following addtional entries will be seen:

 +                Name (ASUN, One)
 +                Method (_DSM, 4, Serialized)  // _DSM: Device-Specific Method
 +                {
 +                    Local0 = Package (0x02)
 +                        {
 +                            BSEL,
 +                            ASUN
 +                        }
 +                    Return (PDSM (Arg0, Arg1, Arg2, Arg3, Local0))
 +                }

similar changes are expected for Q35 modulo:

 -        Field (PCI0.ISA.PIRQ, ByteAcc, NoLock, Preserve)
 +        Field (SF8.PIRQ, ByteAcc, NoLock, Preserve)

and bridge address
