drm/amd/display: Don't overwrite subvp pipe info in fast updates

Browse source

[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
