davinci_emac: use eth_hw_addr_random() instead of random_ether_addr()
Use eth_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.
Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.
Remove one memcpy from emac_dev_setmac_addr() since this is a
duplicate: it's already done some lines above.
v2: use bitops, adapt to eth_hw_addr_random, remove a memcpy
