It should be passed to i3c_device_info when allocating a i3c_dev_desc. Rational behind this change is: when users decide to use SETDASA to assign a dynamic address with exactly the original static address, in step of i3c_master_reattach_i3c_dev, this address is checked to be taken. Then device information retrieving step is skipped. As a result, though the i3c device is registered correctly, its device driver could not be probed. Tested: Tested with a I3C device. If assigned-address is set to be the device's static address, without this change, its device driver could not probed. And with this change, its driver is probed successfully.
