[PATCH v5 1/5] drm/dsi: check for CONFIG_OF when defining of_mipi_dsi_device_add

From: Archit Taneja
Date: Fri Feb 12 2016 - 04:21:24 EST


of_mipi_dsi_device_add is used only when CONFIG_OF is enabled. It
currently works if OF support is disabled, but this will change
when we add more functionality to it.

Define the original func if CONFIG_OF is enabled. Define a dummy func
otherwise.
