 drm/bridge: lvds-codec: Implement atomic_get_input_bus_fmts for LVDS encoder 
atomic_get_input_bus_fmts is only implemented for LVDS decoders, resulting
that LVDS encoders only support bus format MEDIA_BUS_FMT_FIXED. This
results in warnings like:
mxsfb 21c8000.lcdif: Bridge does not provide bus format, assuming
 MEDIA_BUS_FMT_RGB888_1X24.
Please fix bridge driver by handling atomic_get_input_bus_fmts.

Fix this by reusing lvds_codec_atomic_get_input_bus_fmts currently used
for LVDS decoders. Use RGB888_1X24 for LVDS encoders. This also allows
removing the dedicated struct drm_bridge_funcs for decoders.
