msm_fb: display: cleanup usage of shared pipes in overlay

Remove usage of shared pipes. Shared pipes are used to allow VG pipes to
play both video and rgb formats. This can now be handled by calling
overlay set ioctl with new format, that means shared pipes are no longer
needed and can cause instabilities if not used properly.
