[PATCH 08/18] drm/amd/display: patch cases with unknown plane state to prevent warning

From: Swapnil Patel <Swapnil.Patel at amd.com>

[Why]
DCN301 resource function is missing function pointer to
handle cases with unknown plane state.
This causes assertion when global state is validated while
using swizzle parameter as “DC_UNKNOWN”

[How]
Add function pointer to handle and patch cases when plane
state is unknown.
