xhci-pci: Allow host runtime PM as default for Intel Alder Lake xHCI

Browse source

commit b813511135 upstream.

In the same way as Intel Tiger Lake TCSS (Type-C Subsystem) the Alder Lake
TCSS xHCI needs to be runtime suspended whenever possible to allow the
TCSS hardware block to enter D3cold and thus save energy.
