drm/amd/display: Don't overwrite subvp pipe info in fast updates
[Description]
- This is a workaround to avoid concurrency issues -- a fast update
creates a shallow copy of the dc current_state, and removes all
subvp/phantom related flags.
- We want to prevent the fast update thread from removing those
flags in case there's another thread running that requires
the info for proper programming
