drm: Add plane->name and use it in debug prints

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

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