xhci-pci: Allow host runtime PM as default for Intel Maple Ridge xHCI

Intel Maple Ridge is successor of Titan Ridge Thunderbolt controller. As
Titan Ridge this one also includes xHCI host controller. In order to
safe energy we should put it to low power state by default when idle.
For this reason allow host runtime PM for Maple Ridge.
