drm: Add crtc->name and use it in debug messages

Browse source 
Show a sensible name for the crtc in debug mesages. The driver may
supply its own name, otherwise the core genrates the name
("crtc-0", "crtc-1" etc.).

v2: kstrdup() the name passed by the caller (Jani)
v3: Generate a default name if the driver doesn't supply one
