[PATCH 36/40] drm/amd/display: OVT Update on InfoFrame and Mode Management

[Rodrigo Siqueira <Rodrigo.Siqueira@amd.com>]

From: Chris Park <Chris.Park@amd.com>

[Why]
Integrate OVT timing from DM to DC logic to update info frame
and mode management to report the resolution to the OS.

[How]
Reflect RID and Frame Rate to AVI InfoFrame Version 5.
Define new Timing Standard for OVT timing.
