kms equivalent of your patch plus MinPixelClockPLL_Output fix

Ok,
According to your ddx change you have attached to the report, I have changed my
currently more used kms code paths to do the same.

Additionally I have tried to find a way to tweak the pll computation to match
fglrx behaviour and stumbled across the *MinPixelClockPLL_Output having two
alteratives in the firmware info table starting with crev 2. Also looking into
the atombios dump of the card in question, there is a value that might make
more sense than the crev <= 1 value. The attached patch now makes use of that
value and gets exactly the same pll settings that fglrx also used for this
card.

The attached patch contains both changes and is sufficient to make my r520 work
really well.

So, if your BIOS guys told you that the DVO *2 hack is correct, please apply
the attached patch :)

Greetings

Mathias
