Subject: drm/amdkfd: Simplify counting of memory banks
Git-commit: 175b926335c9ce30a531b7a162dde055e7182cbe
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Only count memory banks in one place. Ignore redundant num_banks
entry in crat_subtype_computeunit.
