drm/amd/display: Fix Subvp phantom pipe transition
[Description] - When transitioning a pipe in use (non-phantom) to become a phantom pipe, we must fully disable the pipe first before doing any phantom pipe programming - Move phantom OTG enablement to after "regular" front-end programming sequence (including wait for vupdate) - If a pipe is being transitioned into a phantom pipe, fully disable it first Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
