net: axienet: Utilize of_get_mac_address()
Do not open code getting the MAC address exclusively from the
"local-mac-address" property, but instead use of_get_mac_address()
which looks up the MAC address using the 3 typical property names.
Also avoid casting away the const qualifier of the return value by
making axienet_set_mac_address() take a const void* address.
Follows commit b34296a9c047 ("net: ethoc: Utilize
of_get_mac_address()").
