Subject: drm/radeon: make functions alloc_pasid and free_pasid static
Git-commit: c3fa35a4e5d1a06a5f70e5ac34a05da139aa71f4
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The functions alloc_pasid  and free_pasid are local to the
source and do not need to be in global scope, so make them static.

Cleans up sparse warnings:
warning: symbol 'alloc_pasid' was not declared. Should it be static?
warning: symbol 'free_pasid' was not declared. Should it be static?
