From bbdcc329b8aca375c265e504d55d6c538e9692c1 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3112/4131] drm/amd/display: Use real BE and FE index to
 program regs.

In case of some pipes are fused, pipe_idx should not
be used to program pipe regs. Instead of that, BE and FE
inst number should be used for reg index.
