eth: fwnode: remove the addr len from mac helpers
All callers pass in ETH_ALEN and the function itself will return -EINVAL for any other address length. Just assume it's ETH_ALEN like all other mac address helpers (nvm, of, platform). Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
