*
* - The value of the 'name' property of a virtual-device node
* in the MD is expected to be the same for the corresponding
* OBP device node.
*
* - Find the virtual-device node corresponding to a channel-endpoint
* by walking backwards. Then obtain the values for the 'name' and
* 'cfg-handle' properties.
*
* - Walk all the children of the cnex, find a matching dip which
* has the same 'name' and 'reg' property values.
*
* - The channels that have no corresponding device driver are
* treated as if they correspond to the cnex driver,
* that is, return cnex dip for them. This means, the
* cnex acts as an umbrella device driver. Note, this is
* for 'intrstat' statistics purposes only. As a result of this,
* the 'intrstat' shows cnex as the device that is servicing the
* interrupts corresponding to these channels.
*
* For now, only one such case is known, that is, the channels that
* are used by the "domain-services".
