octeontx2-nicpf: Allow PF to set VF mac address when SR-IOV is disabled

commit 836a62c9312fd456008a603a6666893aa17851fd from
git@git.assembla.com:cavium/WindRiver.linux.git

This patch allows PF driver to modify the VF mac address even
when SR-IOV is not enabled. The AF driver stores the new mac
address and assigns to VF when it is initialized.
