b8b0446f1f dt-bindings: i3c: Describe Silvaco master binding
Silvaco provide a dual-role I3C master.

Description is rather simple: it needs a register mapping, three
clocks and an interrupt.

de67276e66 dt-bindings: i3c: mipi-hci: Include the bus binding
Update a little bit the content to match the bus binding, including:
- the node title should have been named after the description done
  in the historical i3c.txt file, ie: i3c-master@<address>
- child nodes should be accepted even though the drivers do not currently
  support it
- #address-cells and #size-cells are also mandatory and have specific
  values

c307912d28 dt-bindings: i3c: MIPI I3C Host Controller Interface
The MIPI I3C HCI (Host Controller Interface) specification defines
a common software driver interface to support compliant MIPI I3C
host controller hardware implementations from multiple vendors.

All that is needed is an I/O area and an interrupt signal;. The hardware
is self-advertising wrt its implementor and implemented capabilities so
there is currently no details that the driver can't figure out on its own.
