Subject: [PATCH 02/16] driver core: Rename get_dev_from_fwnode() wrapper to get_device_from_fwnode()

get_dev_from_fwnode() calls get_device() and so it acquires a reference
on the device returned.

In order to be more obvious that this wrapper is a get_device() variant,
rename it to get_device_from_fwnode().
