Comment 4 for bug 1262033

Base on the fwts log on the comment#3

there are 3 critical failures that come from buggy firmware,
 method: Detected error 'Not found' when evaluating '\_SB_.PCI0.RP05.PEGP.DD02._BCL'.
 method: Detected error 'Not found' when evaluating '\_SB_.PCI0.RP05.PEGP.DD02._BCM'.
 method: Detected error 'Not found' when evaluating '\_SB_.PCI0.RP05.PEGP.DD02._BQC'.

this is due to the _BCL, _BCM, _BQC method from device \_SB_.PCI0.RP05.PEGP.DD02 will invoke the _BCL, _BCM, _BQC from device _SB.PCI0.GFX0.DD02
            Method (_BCL, 0, NotSerialized)
            {
                Return (\_SB.PCI0.GFX0.DD02._BCL)
            }

            Method (_BQC, 0, NotSerialized)
            {
                Return (\_SB.PCI0.GFX0.DD02._BQC)
            }

            Method (_BCM, 1, NotSerialized)
            {
                Return (\_SB.PCI0.GFX0.DD02._BCM)
                Arg0
            }

but there are no _BCL, _BCM, _BQC methods defined on device _SB.PCI0.GFX0.DD02
