drm/imx: Remove encoders' ->prepare callbacks
The main task of imx encoders' ->prepare callbacks is to set bus_format, bus_flags, di_vsync_pin and di_hsync_pin. We may create a structure named imx_encoder to cache them. The atomic encoder callback ->disable may replace ->prepare later, so let's remove ->prepare.
