Implement .atomic_get_input_bus_fmts callback, which sets up
the input (scanout-engine-end) formats, so that those formats
can then be used in pipeline format negotiation between this
bridge and the scanout engine.

drm/i915 target adds some extra cflags, especially it does re-apply -Wall.
In clang this will override -Wno-format-security and cause the build to
fail when CONFIG_DRM_I915_WERROR=y. While with GCC this does not happen.
We reapply -Wno-format-security here to get around this issue.
