[PATCH 1/1][SRU][OEM-5.6] xhci-pci: Allow host runtime PM as default for Intel Tiger Lake xHCI

[Koba Ko]

From: Mika Westerberg <mika.westerberg at linux.intel.com>

BugLink: https://bugs.launchpad.net/bugs/1878149

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