The ENTDAA does not have a way to assign DA that are with a PID. It will
assign DAs that were in it's RRs in the order that they win arbitration.
Assign only available addresses in to it's RRs before ENTDAA.
Cleanup the attach api to no longer require a addr argument and remove
the helper function `i3c_determine_default_addr`. This now looks at if
it has a static address or if it already has a dynamic address (such as
from DEFTGTS) and will register the address if either exist with
precidence of dynamic addr over static addr.
This also fixes up the look up for if a device already has a dynamic
addr to find which pos of the RRs is it is in.
