target: msm8953: add support to set no panel configuration
Add support to skip splash screen and set panel to none. If the
panel name is none, the probe fails for both the dsi controllers and
fb is not initialized. The feature is provided for usecases where
there is no need for display driver to be initialized. This feature
is needed for both msm8953 and apq8053 platforms.
