drm/amd/gfx: add instance field to select_se_sh (v3)
Add ability to specify instance in select_se_sh callback. Defaults to 0xffffffff all over the driver. (v2) Don't enable INSTANCE_BROADCAST by default (v3) Style changes Signed-off-by: Tom St Denis <tom.stdenis@amd.com> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
