CNB: eth: fwnode: remove the addr len from mac helpers
Bugzilla: http://bugzilla.redhat.com/2069566
Tested: build, boot
Update function helpers device_get_mac_address
and fwnode_get_mac_address
, making them returning and errno instead of a pointer and not having to pass the buffer length which is always ETH_ALEN
.
