CMN-600 uses bits [27:0] for child node address offset while bits [30:28]
are required to be zero.

For CMN-650, the child node address offset field has been increased
to include bits [29:0] while leaving only bit 30 set to zero.

Let's include the missing two bits and assume older implementations
comply with the spec and set bits [29:28] to 0.
