drm/mipi-dsi: pass DSC data through the struct mipi_dsi_device 

The commit 0f40ba48de ("drm/msm/dsi: Pass DSC params to drm_panel")
added a pointer to the DSC data to the struct drm_panel. However DSC
support is not limited to the DSI panels. MIPI DSI bridges can also
consume DSC command streams. Thus add struct drm_dsc_config pointer to
the struct mipi_dsi_device.
