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.
[1] CEA-861-E - 5.1 Default Encoding Parameters
[2] VESA DisplayPort Ver.1.2a - 5.1.1.1 Video Colorimetry
v2: Use has_hdmi_sink to check if a HDMI monitor is present
v3: Add information about relevant spec chapters
