This is a preparation for HDMI hotplug support. This patch just moves all platform defined video modes for the sh_mobile_lcdcfb driver to separate arrays and switches all users to use element 0 of that array, so, this patch doesn't introduce any functional changes and as such should not cause any regressions.
