drm/dsi: Check for CONFIG_OF when defining of_mipi_dsi_device_add()

Browse Source 
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 function if CONFIG_OF is enabled and a dummy
function otherwise.
