[PATCH v1 3/3] driver core: Split device related fwnode API to device/fwnode.h

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

device.h is a huge header which is hard to follow and easy to miss
something. Improve that by splitting device related fwnode API
to device/fwnode.h.

In particular this helps to speedup the build of the code that includes
device.h solely for a device related fwnode API.
