Subject: drm/exynos/dsi: propagate info about command mode from panel
Git-commit: c038f53842cf840889473d219ace7f9121694e8d
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

mipi_dsi framework provides information about panel's mode of work.
This info should be propagated upstream to configure all elements of
the pipeline. As CRTC is the common denominator of the pipeline we can
put such info into its structures.
