DE2 SoCs can support LCDs up to 1080p (e.g. A64), and 3MHz step won't let PLL_VIDEO be high enough for them.
Use 6MHz step for PLL_VIDEO when using DE2, to satisfy 1080p LCD.

I wonder if this will cause any issues with panels and lower resolutions that will have a smaller tolerancy.
Does it impact lower resolution panels? is it tested?
It works fine with 1366x768 panel, and I don't have any other panels that work in u-boot to test. And correct me if I'm wrong but I don't think that we have any boards with DE2 and low-res panel supported in u-boot.
ie what I wonder too, if we have any thing similar for DE2. anyway
