This patch adds support for the below mentioned pixel clocks in Exynos5250. Without them, following display modes won't be supported:
71 MHz - 1280x800@60Hz RB 73.25 MHz - 800x600@120Hz RB 88.75 MHz - 1440x900@60Hz RB 115.5 MHz - 1024x768@120Hz RB 119 MHz - 1680x1050@60Hz RB

We should probably remove it here as well.

I have informed this issue to the hardware team, and will update it once i receive any changes, Also i
