[PATCH] drm/panel: simple: Simplify matching using of_device_get_match_data()

[Geert Uytterhoeven]

Both the patform_driver and mipi_dsi_driver structures contain pointers
to the match table used, so the custom code to obtain match and match
data can be replaced by calls to of_device_get_match_data().
