Currently, mode_fixup code doesn't consider the limitations of mixer as it is implemented inside the hdmi driver. Following fix, moves the mode_fixup to common drm hdmi driver. To check the mode support, it calls both, mixer and hdmi check_timing callbacks for a given resolution mode. This patch is dependent on https://patchwork.kernel.org/patch/2176021/.
