<title>drm/amd/display: Disable MPC rate control on ODM pipe update</title>

<id>83626efdce0be2eb80696110fe55e9290c72b1f1</id>
<content type='text'>
[Why]
Seamless boot skips MPC init for the active pipe, resulting in stale MPC
rate control state being retained. This will cause issues since other
logic assumes it is disabled (as DCN30 and newer does not need it).

[How]
Disable MPC rate control on ODM pipe update to cover the seamless boot
case.
