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.
