i2c: qcom-cci: drop custom suspend/resume and rely on runtime PM helpers
cci_resume() unconditionally calls cci_resume_runtime() regardless of
the runtime PM state.

If the device is already runtime-suspended before system suspend,
the clock is re-enabled while runtime_status remains RPM_SUSPENDED.
As a result, pm_request_autosuspend() does not arm the timer,
leaving the clock permanently enabled.
