drm/amd/display: Disable phantom OTG after enable for plane disable
[Description]
- Need to disable phantom OTG after it's enabled
in order to restore it to it's original state.
- If it's enabled and then an MCLK switch comes in
we may not prefetch the correct data since the phantom
OTG could already be in the middle of the frame.
