dm: core: device: add function: dev_get_driver_ops()
This commit extends the driver model device's API by function:
- dev_get_driver_ops()
And this function returns the device's driver's operations if given:
- dev pointer, is non-NULL
- dev->driver->ops pointer, is non-NULL
in other case the, the NULL pointer is returned.
