Add LCD Panel support for iWave RZ/G1E board based on r8a7745 SoC.
Backporting the panel patch as it is, requires drm bridge Api changes, which is not present at 4.4 kernel. So used the 4.4 rm framework to attach the simple panel driver with rgb connector driver. The rgb connector is based on the workdone for the lvds connector. The display panel binding patch is backported to 4.4 kernel,since the mainline uses yaml file and it conflict with corresponding .txt in 4.4 kernel.
Other patches in this series are cherry picked from mainline.
I don't see anything wrong with this, so I'll test/apply it if noone objects.
I guess we could like patches for cip-kernel-config repository to actually enable this in our testing...
