On my HiKey board, I'm seeing clk warnings on suspend/resume,
which seem to be caused by runtime pm suspending the device,
then the same suspend hook being called again on suspend time.
This patch fixes this by setting the SYSTEM_SLEEP_PM_OPS to
using pm_runtime_force_suspend and pm_runtime_force_resume.
