Network subsystem NetCP in Keystone-2 devices includes some HW blocks
that are memory mapped to ranges outside that of the NetCP itself.
Thus address space of a child node of the NetCP node needs to be
mapped 1:1 onto the parent address space. Hence empty ranges
should be used under the NetCP node.

What blocks are we talking here. We need to increase the
range if the current range isn't covering entire NETCP
address space. Removing range isn't a solution.
