Christian Schmidt 54ac76f851 drm/edid: support CEA video modes. 
TFT/plasma televisions and projectors have become commonplace, and so
has the use of PCs to drive them. Add the video modes specified by an
EDID's CEA extension to the mode database for a connector.

Chris Wilson b1f559ecdc drm: Mark constant arrays of drm_display_mode const 
... and fixup some methods to accept the constant argument.

const appropriately has some benefits beyond warning the programmer
about likely mistakes.
