[Intel-gfx] [PATCH v4 15/15] drm/i915/glk: set HDMI 2.0 identifier

[Shashank Sharma]

This patch sets the is_hdmi2_src identifier in drm connector
for GLK platform. GLK contains a native HDMI 2.0 controller.
This identifier will help the EDID handling functions to save
lot of work which is specific to HDMI 2.0 sources.

V3: Added this patch
V4: Rebase
