Introduce add_disk_fwnode() as a replacement of device_add_disk() that permits to pass and attach a fwnode to disk dev. This variant can be useful for eMMC that might have the partition table for the disk defined in DT. A parser can later make use of the attached fwnode to parse the related table and init the hardcoded partition for the disk. device_add_disk() is converted to a simple wrapper of add_disk_fwnode() with the fwnode entry set as NULL.
