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.
