From: Boyuan Zhang <boyuan.zh...@amd.com>

For vcn 2_5, add ip_block for each vcn instance during discovery stage.

And only powering on/off one of the vcn instance using the
instance value stored in ip_block, instead of powering on/off all
vcn instances. Modify the existing functions to use the instance value
in ip_block, and remove the original for loop for all vcn instances.

v2: rename "i"/"j" to "inst" for instance value.
