drm/panel: simple: Assign data from panel_dpi_probe() correctly
In the function panel_simple_probe() the pointer panel->desc is
assigned to the passed pointer desc. If function panel_dpi_probe()
is called panel->desc will be updated, but further on only desc
will be evaluated. So update the desc pointer to be able to use
the data from the function panel_dpi_probe().
Fixes: 4a1d0dbc8332 ("drm/panel: simple: add panel-dpi support")
