Added device power management hook infrastructure. Added DEVICE_INIT_PM and SYS_INIT_PM macros that creates device structures with the supplied device_ops structure containing the hooks. Added example support in gpio_dw driver. Updated the sample app and tested using LPS and Device Suspend Only policies.
