Subject: [PATCH 2/2] media: dt-bindings: samsung-fimc: drop simple-bus

The FIMC camera node wrapper is not a bus, so using simple-bus fallback
compatible just to instantiate its children nodes was never correct.
Drop the simple-bus compatible and expect driver to explicitly populate
children devices.
