drm/mipi-dsi: move to_mipi_dsi_device() to use container_of_const()

The driver core is changing to pass some pointers as const, so move to_mipi_dsi_device() to use container_of_const() to handle this change. to_mipi_dsi_device() now properly keeps the const-ness of the pointer passed into it, while as before it could be lost.
