Changing from lvds issue to more general encoder issue.

Tracking issue here: ​https://docs.google.com/spreadsheet/ccc?key=0Arnu-hcq_YP7dFBPcHppeTQ2b0hXeG81c1dYb2RLNVE

This seems more like a general issue with mode setting on cards with Kaleidoscope encoders after correlating the issues.

I am standing up a test machine with Kaleidoscope encoders to try and reproduce the issue.

    v7 v17  
    1 We need to generate fake edid information based on the output of a special LVDS information AtomBIOS call.
     1It seems hardware with Kaleidoscope encoders are consistently seeing mode setting issues.

    3 The lack of this information prevents several laptop LCD displays from modesetting properly.
