A network driver should not touch the environment at all. This patch fixes
this behaviour by removing the code for setting a default/randomized MAC
address.

Instead a board should either set CONFIG_ETHADDR, CONFIG_ETH1ADDR etc. or
use some specific code within the board files, eg. if randomization is
needed.

All boards which have CONFIG_SKIP_LOCAL_MAC_RANDOMIZATION set (actually its
only one board, edminiv2) are converted to use CONFIG_ETHADDR. Please check
your boards whether you really need randomization support or the
CONFIG_ETHADDR macro is enough.
