[PATCH v2] i2c: designwear: Fix clk warning on suspend/resume

[John Stultz <john.stultz@linaro.org>]

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.
