System suspend uses pm_runtime_force_suspend(), which cheekily bypasses
the runpm reference counts. This doesn't actually work so well when the
GPU is active. So add a reasonable delay waiting for the GPU to become
idle.

System suspend uses pm_runtime_force_suspend(), which cheekily bypasses
the runpm reference counts. This doesn't actually work so well when the
GPU is active. So add a reasonable delay waiting for the GPU to become
idle.
Alternatively we could just return -EBUSY in this case,
