Exynos G2D driver is the last client of the custom Exynos 'sub-driver' framework. In the current state it doesn't really resolve any of the issues it has been designed for, as Exynos DRM is already built only as a single kernel module. Remove the custom 'sub-driver' framework and simply use generic component framework also in G2D driver.
