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.
