[RFC 2/5] drm: uapi: Add HDMI 2.0 aspect ratio flags and HDMI 2.0+ mode flag

[Jose Abreu]

Add the HDMI 2.0 aspect ratio flags (64:27 and 256:135) and a new
flag which will signal userspace that this is a HDMI 2.0+ mode. It
is expected that these new flags will not be exported to userspace
unless client asks to.
