dpaa2-mac: workaround for zero advertising on the MAC

It seems there are some circumstances in the latest MC firmware versions
where an empty advertising field is returned by the dpmac_get_link_cfg()
command. This will eventually lead to the link not going up.
Work around this issue by skipping PHY reconfiguration if this happens.
