During the initialization of the DSI protocol registers, we always set
the sources of all DSI channels to L4. However, we don't update the
value in the dsi_data, so we may end up with a different value in the
register and in the dsi_data, leading to DSI problems.

This patch fixes the issue by initializing also the channel source in
the dsi_data.
