[PATCH] hwmon: tmp102: add hibernation callbacks

[grygorii.strashko at linaro.org]

From: Grygorii Strashko <Grygorii.Strashko at linaro.org>

Setting a dev_pm_ops suspend/resume pair but not a set of
hibernation functions means those pm functions will not be
called upon hibernation.
Fix this by using SIMPLE_DEV_PM_OPS, which appropriately
assigns the suspend and hibernation handlers.
