drm/msm/sde: continue with hw init if splash memory is not found 



For continuous splash screen disabled use cases, it is possible that
no reserved memory region for the splash screen buffer is specified.
In such cases, set software sate to continuous splash disabled and
continue with the driver hardware initialization sequence.
