This patch introduces amdgpu_userqueue_object and its helper
functions to creates and destroy this object. The helper
functions creates/destroys a base amdgpu_bo, kmap/unmap it and
save the respective GPU and CPU addresses in the encapsulating
userqueue object.
These helpers will be used to create/destroy userqueue MQD, WPTR
and FW areas.
V7:
- Forked out this new patch from V11-gfx-userqueue patch to prevent
that patch from growing very big.
- Using amdgpu_bo_create instead of amdgpu_bo_create_kernel in prep
for eviction fences (Christian)
V9:
- Rebase
V10:
- Added Alex's R-B
