i3c: master: Do not add device for HUB
Current implementation tries to add device for each DT entry. In case
I3C HUB we do not want add device 'manually', using DT. I3C HUB shall
be discovered dynamically. But DT entry for I3C HUB is required. Thus
master driver shall not add device for HUB entry in DT.
