This does not work since the i2c core wont look at the legacy pm callbacks if a driver has the 'pm' field set. This patch fixes it by moving over to dev_pm_ops for suspend/resume as well. Since both runtime pm and suspend/resume behave the same way this can easily be done using the UNIVERSAL_DEV_PM_OPS macro.
