Subject: drm/amd/display: Fix warning. Set MAX_SURFACES to 3
Git-commit: 091a97e542cf9a9af6e48aa1324044433ea7341a
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Currently we never use more than 2 surfaces in all use cases.
This avoids pushing dc_commit_surfaces_to_target beyond a
stacksize of 1024.
