vcn code is restructured for per instance basis. Each
vcn instance is represented by an ip_block and hence a
need to update the dump and print functions for each
instance as an IP.
Existing way was to capture the ip dump for each instance
in a same memory dump but now each ip_block of vcn is an
independent one and its memory is independent and handled
within the ip_block now.
