[PATCH 5.17 032/772] xhci: Allow host runtime PM as default for Intel Alder Lake N xHCI

[Greg Kroah-Hartman]

From: Mathias Nyman <mathias.nyman@xxxxxxxxxxxxxxx>

commit 74f55a62c4c354f43a6d75f77dd184c4f57b9a26 upstream.

Alder Lake N TCSS xHCI needs to be runtime suspended whenever possible
to allow the TCSS hardware block to enter D3 and thus save energy
