drm: Add and handle new aspect ratios in DRM layer
HDMI 2.0/CEA-861-F introduces two new aspect ratios:
- 64:27
- 256:135
This patch:
- Adds new DRM flags for to represent these new aspect ratios.
- Adds new cases to handle these aspect ratios while converting
from user->kernel mode or vise versa.
V2: Rebase
V3: Align macro for DRM_MODE_PICTURE_ASPECT_256_135 (Jim Bride)
V4: Added r-b from Jose.
