drm/i915: Add "Automatic" mode for the "Broadcast RGB" property
Add a new "Automatic" mode to the "Broadcast RGB" range property. When selected the driver automagically selects between full range and limited range output. Based on CEA-861 [1] guidelines, limited range output is selected if the mode is a CEA mode, except 640x480. Otherwise full range output is used. Additionally DVI monitors should most likely default to full range always. As per DP1.2a [2] DisplayPort should always use full range for 18bpp, and otherwise will follow CEA-861 rules. NOTE: The default value for the property will now be "Automatic" so some people may be affected in case they're relying on the current full range default.
