parentdrm/imx: Remove encoders' ->prepare callbacks (diff)

drm/imx: atomic phase 3 step 1: Use atomic configuration
Replacing drm_crtc_helper_set_config() by drm_atomic_helper_set_config() and converting the suspend/resume operations to atomic make us be able to use atomic configurations. All of these allow us to remove the crtc_funcs->mode_set callback as it is no longer used. Also, change the plane_funcs->update/disable_plane callbacks from the transitional version to the atomic version. Furthermore, switching to the pure atomic version of set_config callback means that we may implement CRTC/plane atomic checks by using the new CRTC/plane states instead of the legacy ones and we may remove the private ipu_crtc->enabled state which was left there for the transitional atomic helpers in phase 1. Page flip is also switched to the atomic version. Last, the legacy function drm_helper_disable_unused_functions() is removed from ->load in order not to confuse the atomic driver.
