[U-Boot] [PATCH 21/27] cmc_pu2: get mac address from environment

[Mike Frysinger]

The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.

Also rename load_sernum_ethaddr() to misc_init_r() so we don't need to
handle this board specially in common ARM code.
