drm/amdgpu: Add kgd/kfd interface to support scratch memory v2

Browse Source 
v2:
* Shortened headline
* Removed write_config_static_mem, it gets initialized by gfx_v?_0_gpu_init
* Renamed alloc_memory_of_scratch to set_scratch_backing_va
* Made set_scratch_backing_va a void function
* Documented set_scratch_backing in kgd_kfd_interface.h
