[PATCH v2 08/13] drm/panel-samsung-s6e88a0-ams452ef01: 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).
