[PATCH] crypto: cavium/nitrox - Fix HW family part name format

[Nagadheeraj Rottela]

This patch fixes the NITROX-V family part name format. The fix includes
ZIP core performance (feature option) in the part name to differentiate
various HW devices. The complete HW part name format is mentioned below

Part name: CNN55<core option>-<freq>BG676-<feature option>-<rev>
