Subject: drm/nouveau/core/memory: add mechanism to retrieve allocation
 granularity
Git-commit: 2c9c4910f8b126d18fa2a08087f3ae1553e706bc
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Needed by VMM code to determine whether an allocation is compatible with
a given page size (ie. you can't map 4KiB system memory pages into 64KiB
GPU pages).
