Fix wakeup problems on some AMD platforms

Problems have been reported on AMD laptops with suspend/resume where particular root ports are put into D3 and then the system is unable to resume properly. The issue boils down to the currently selected kernel policy for root port behavior at suspend time: 0) If the machine is from 2015 or later 1) If a PCIe root port is power manageable by the platform then platform will be used to determine the power state of the root port at suspend. 2) If the PCIe root is not power manageable by the platform then the kernel will check if it was configured to wakeup. 3) If it was, then it will be put into the deepest state that supports wakeup from PME. 4) If it wasn't, then it will be put into D3hot. This series adjusts it so only root ports that are power manageable by the platform will be considered for being put into D3.
