Subject: drm/amd/display: fix bw_calc_auto translation error
Git-commit: afa80d64d20ac13528c261e1233ac3982609fd2f
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The compiler was warning about conditions that will never evaluate
to true. The problem was that the VBA translater didn't translate
the conditions correctly.
