drm/omap: Move bus flag hack to encoder implementation
The bus flags stored in omap_dss_device instances are used to fixup the video mode before setting it, to honour constraints that can't be expressed through drm_display_mode. The fixup occurs in the CRTC mode set operation and the resulting video mode is stored internally in the CRTC. It is then used next by omap_encoder_enable() to apply mode fixups for the omap_dss_device instances in omap_encoder_update(). Move the hack to the omap_encoder_update() function right before applying the omap_dss_device fixups, in order to group all fixups together.
