[PATCH 08/12] drm/amd/display: program output tf when required

[jdhillon]

From: Dillon Varone <Dillon.Varone at amd.com>

[Description]
Output transfer function must be programmed per pipe as part of a front end
update when the plane changes, or output transfer function changes for a
given plane.
