thunderbolt: Add runtime PM for Software CM
This adds runtime PM support for the Software Connection Manager parts
of the driver. This allows to save power when either there is no device
attached at all or there is a device attached and all following
conditions are true:
- Tunneled PCIe root/downstream ports are runtime suspended
- Tunneled USB3 ports are runtime suspended
- No active DisplayPort stream
- No active XDomain connection
For the first two we take advantage of device links that were added in
previous patch. Difference for the system sleep case is that we also
enable wakes when something is geting plugged in/out of the Thunderbolt
ports.
