When the I3C subsystem wants to assign a dynamic address using the SETDASA
CCC, it needs to attach the I3C device with device info that includes only
the static address. In the HCI, if the driver want to send this SETDASA
CCC, a DAT entry is required to temporarily fill the device's static
address into the dynamic address field. Afterward, the reattach API will
be executed to update the DAT with the correct dynamic addrees value.

(Minor comment to the subject. Is this rather fix than support SETDASA?)
