patch 1/3

I think this entire patch set should be applied.  First patch switches to 64
bit math for the cts calcuation.  Second patch patches the radeon acr tables
based on the clock values generated by the drm code that generates the 1001
modes. Third patch enables hw generated cts and n values.  If there are indeed
problems with using the hw generated values, we can disable the 3rd patch on
the problematic asics, and the other two patches should do the right thing.
