[PATCH] driver: move some inline getters for struct device into device.h

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The purpose of device.h is to contain only the device related
definitions and have as few header dependencies as possible.

dev_of_node() and dev_is_dma_coherent() are accessors for struct device
and have no other dependencies, so move them into this header as well.
