PS2:
> Do you know where we are setting the _STA for RTD3 power resource to `1`? […]

this function pcie_rtd3_acpi_method_status will create below acpi code

it will return 1 if power pin is up

Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                0x6E = _SB.PCI0.GTXS /* External reference */
                Local0
                Local1 = Zero
                If ((Local0 == Local1))
                {
                    Return (Zero)
                }
                Else
                {
                    Return (One)
                }
            }
