octeontx2-af: Handle PF-VF mac address changes
This patch handles the VF mac address changes as given below.
1. mac addr configrued by VF will be retained until VF module unload.
2. mac addr configred by PF for VF will be retained until power cycle.
3. mac addr confgired by PF for its VF can't be overwritten by VF.
