[PATCH v3 12/28] driver core: fw_devlink: Tag the fwnode dev member as private

[Herve Codina]

The dev member in the fwnode structure should be accessed only by the
fwnode core. The fw_devlink_set_device() helper has been introduced to
avoid users to set this member directly. All users have been converted
and use fw_devlink_set_device() to set the field.

To avoid future abusers who might set the field directly and allow
sparse to detect them, tag the dev field as a private field.
