drm/amdgpu: add get_gfx_shadow_info callback for gfx11
Used to get the size and alignment requirements for the gfx shadow buffer for preemption. v2: use FW version check to determine whether to return a valid size here return an error if not supported (Alex) v3: drop GDS (Alex) v4: make amdgpu_gfx_shadow_info mandatory (Alex) Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
