[PATCH v2 13/13] drm/panel-xinpeng-xpp055c272: Drop custom DSI write macro

From: Javier Martinez Canillas
Date: Sat Jan 07 2023 - 14:21:11 EST


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).
- Fix generic DSI and DCS commands write discrepancy (Sam Ravnborg).
