drm/amdgpu: Merge amdkfd into amdgpu
Since KFD is only supported by single GPU driver, it makes sense to merge amdgpu and amdkfd into one module. This patch is the initial step: merge Kconfig and Makefile. v2: also remove kfd from drm Kconfig Signed-off-by: Amber Lin <Amber.Lin@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
