kms/device: Add functions to find connector and crtc in devices

Browse Source 
Hotplug events may contain CRTC or CONNECTOR ids to notify a property
change to just one owner, so we need to find its parent device.

Also we may want to update properties directly without having to go through
all the devices, so expose a simple way to find them.
