blackfin: replace bfin_gen_rand_mac() with eth_random_addr()

Browse Source 
bfin_gen_rand_mac() uses __DATE__ as the seed for random ethernet
address. This makes the build non-deterministic.

In the first place, it should not be implemented as a Bfin-specific
function. Use eth_random_addr() instead.
