drm/amdgpu: add kernel config for gfx-userqueue
This patch:
- adds a kernel config option "CONFIG_DRM_AMDGPU_NAVI3X_USERQ"
- moves the usequeue initialization code for all IPs under
this flag
- cover the core userqueue functions under this config
- adds stub function for userqueue ioctl.
so that the userqueue works only when the config is enabled.
V9: Introduce this patch
V10: Call it CONFIG_DRM_AMDGPU_NAVI3X_USERQ instead of
CONFIG_DRM_AMDGPU_USERQ_GFX (Christian)
V11: Add GFX in the config help description message.
V12: Add depends on BROKEN for this config, remove this when the rest of
the code is available.
