The function __fw_devlink_pickup_dangling_consumers() intends to ignore suppliers that are already capable of probing, but uses whether or not a bus struct is defined in the device struct. There are some cases where a firmware child node can be address translatable but not able to probe (e.g. the use of of_platform_populate() for MTD partitions), so whether or not a driver is present is a more accurate way to guess whether a fwnode represents a real probing device here. This also serves as a preparation step for further changes to fw_devlink including making the contents of this function less strict in order to compensate for more cases being passed into the rest of the function because the return case is now more strict.
