b9f1b45bac i2c-puv3: Use struct dev_pm_ops for power management
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.

This patch converts the driver to use the module_platform_driver()
macro which makes the code smaller and a bit simpler.
