xhci: Use pm_runtime_get to prevent RPM on unsupported systems

Use pm_runtime_put in the remove function and pm_runtime_get to disable
RPM on platforms that don't support runtime D3, as re-enabling it through
sysfs auto power control may cause the controller to malfunction. This
can lead to issues such as hotplug devices not being detected due to
failed interrupt generation.
