[PATCH 2/3] fbdev: mxsfb: Return ENODEV on missing display node

When this driver encounters drm-style bindings it returns -ENOENT and
this reports a probe error. Make it return -ENODEV to signal an explicit
rejection instead.

This allows peaceful coexistence between the DRM_MXSFB and FB_MXS config
options.
