drm/amd/display: Merge pipes for validate
Validation expects to operate on non-split pipes. This is
seen in dcn20_fast_validate_bw, which merges pipes for
validation. We weren't doing that in the non-fast path
which lead to validation failures when operating with
4-to-1 MPC and a writeback connector.
