Merge branch 'pci/hotplug'

- Enable pciehp by default if USB4 is enabled because USB4/Thunderbolt
  tunneling depends on native PCIe hotplug (Albert Zhou)

- Make sure pciehp binds only to Downstream Ports, not Upstream Ports
  (Rafael J. Wysocki)

- Remove unused get_mode1_ECC_cap callback in shpchp (Ian Cowan)

- Enable pciehp Command Completed Interrupt only if supported to reduce
  confusion when looking at lspci output (Pali Rohár)
