Currently every time a vendor introduces a new USB4 controller changes
need to be made in xhci-pci to add the PCI IDs representing the XHCI
controller used for tunneling.

Due to low power management needs every single integrated Intel and
AMD controller have needed to be added.  Recent discussions have come
at using the xHC interface version to decide that runtime PM should
be enabled.

v1->v2:
 * Drop existing patches
 * New patches to use xHC interface version instead

Mario Limonciello (2):
  xhci-pci: Set runtime PM as default policy on all xHC 1.2 or later
    devices
  xhci-pci: Lower the requirement for runtime PM version to 1.0
