drm/amdgpu/display: Implement functions to let DC allocate GPU memory
[Why]
DC needs to communicate with PM FW through GPU memory. In order
to do so we need to be able to allocate memory from within DC.
[How]
Call amdgpu_bo_create_kernel to allocate GPU memory and use a
list in amdgpu_display_manager to track our allocations so we
can clean them up later.
