[PATCH v2 04/13] drm/panel-elida-kd35t133: Drop custom DSI write macro

[Javier Martinez Canillas]

There is a macro for this already in the <drm/drm_mipi_dsi.h> header, use
that instead and delete the custom DSI write macro defined in the driver.

Changes in v2:
- Add Sam Ravnborg's Reviewed-by tag.
- Fix identation on macro usage (Sam Ravnborg).
