[PATCH 5/7] i2c-puv3: Use struct dev_pm_ops for power management

["Rafael J. Wysocki" <rjw@sisk.pl>]

From: Rafael J. Wysocki <rjw@sisk.pl>

Make the PKUnity-v3 SoC I2C controller driver define its suspend
callback through a struct dev_pm_ops object rather than by using
a legacy PM hook in struct platform_driver.  The empty resume
callback is not necessary, so remove it.
