drm/exynos: Pass exynos_drm_manager in manager ops instead of dev
This patch changes the manager ops callbacks from accepting the subdrv device pointer to taking a pointer to the manager. This will allow us to move closer to decoupling manager/display from subdrv, and subsequently decoupling the crtc/plane from the encoder.
