Subject: drm/amdkfd: initialise kfd inside amdgpu_device_init
Git-commit: 1884734a03904d23137a075c9b64cd9871af1914
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Also finalize kfd inside amdgpu_device_fini. kfd device_init needs
SRIOV exclusive accessing. Try to gather exclusive accessing to
reduce time consuming.
