This reverts commit 06a2f5c2c4e0cb4ff38ca3769ae1f81cc2d030cf and f7c2f36f4395f12d8ecb25c28ee88ec87b457089.
These two patches were trying to fix an issue that was causing an infinite loop at the load of the exynos-drm but they were not tackling the source of the problem.
A new patch that move the platform driver registration exynos_drm_init() follows this revert and fix the issue properly.
