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. Signed-off-by: Rafael J.
