drm/amd/display: Fix rest of pass-by-value structs in DML

Passing structs adds a lot of overhead. We don't ever want to pass
anything bigger than primitives by value.

This patch fixes these Coverity IDs:
Addresses-Coverity-ID: 1424031: ("Big parameter passed by value")
Addresses-Coverity-ID: 1424055: ("Big parameter passed by value")
Addresses-Coverity-ID: 1424072: ("Big parameter passed by value")
Addresses-Coverity-ID: 1423779: ("Big parameter passed by value")
