From: Shashank Sharma <shashank.sharma@xxxxxxxxx> In plane enabling sequence, plane gamma bit is by default enabled. Plane gamma gets higher priority than pipe gamma, if both enabled. This patch disables plane gamma from sequence. If required, plane gamma can be enabled via the color manager drm interface.
