[PATCH 0/5] Add aspect ratio parsing

Currently DRM framework doesn't parse aspect ratio of a videomode
while converting it from a umode->kmode or viceversa. This causes
modeset of CEA modes with incorrect aspect ratio.

While running HDMI complaince, tests (like 7-27) expect the DUT
to apply the mode as per the VIC, but as driver does not consider
the aspect ratio part while searching a mode from modedb, we end
up setting mode with a wrong VIC, causing the test to fail.

What this patch set does:
Patch 1-2
- Adds aspect ratio flags in the DRM layer, in form of flags.
- Adds parsing of aspect ratio, during conversion of a umode->kmode
  and viceversa.
- Adds aspect ratio check while finding a mode, during modeset.

Patch 3-5
- Adds some new aspect ratio defined in CEA-861-F specs to
  support HDMI 2.0 displays, in DRM and I915 layer.
