drm/exynos: decon: Add support for hardware windows no 4 and 5
Enable support for 2 more hardware windows. This require enabling a few more clocks and set proper plane type for all windows. In the new configuration primary plane uses hardware window no 3 and cursor uses window no 5. The remaining hardware windows are used for overlays. This gives us an overlay plane both below and above primary plane for both Decon and DeconTV (which uses hardware window nr 0 for background).
