This is for setting up I3C controller device driver instance
and also to perform bus initialization (e.g. dynamic address
assignment).
Note that this needs to be done before the device driver
instances of the connected I2C and I3C devices start
initializing those devices. This is because some devices
may not be addressable until addresses are assigned by
the controller.
