net: atlantic: unify MAC generation
This patch unifies invalid MAC address handling with other drivers. Basically we've switched to using standard APIs (is_valid_ether_addr / eth_hw_addr_random) where possible. It's worth noting that some of engineering Aquantia NICs might be provisioned with a partially zeroed out MAC, which is still invalid, but not caught by is_valid_ether_addr(), so we've added a special handling for this case. Also adding a warning in case of fallback to random MAC, because this shouldn't be needed on production NICs, they should all be provisioned with unique MAC. NB! Default systemd/udevd configuration is 'MACAddressPolicy=persistent'. This causes MAC address to be persisted across driver reloads and reboots. We had to change it to 'none' for verification purposes.
