Define a MCTP bus binding for i3c controller

This bus binding make use of IBI interrupt signaling from targets to signal their desire to send a message. The binding specification (dsp0233 v1.0.1) offers alternative modes of operaton such as polling or directly reading but these are not implemented.

Parameters

_name	Symbolic name of the bus binding variable
_node_id	DeviceTree Node containing the configuration of this MCTP binding
