of: Modify of_device_get_modalias to be passed struct device
Now that the of_node pointer is part of struct device,
of_device_get_modalias could be used on any struct device
that has the device node pointer set. This patch changes
of_device_get_modalias to accept a struct device instead
of a struct of_device.
