[U-Boot] [PATCH v2] omap3evm: Set environment variable 'ethaddr'

[Sanjeev Premi]

It is now responsibility of the board specific init
code to set the environment variable corresponding
to the MAC address.

   Changes in v2:
   - Ensure that environment variable is set iff
     it wasn't already set earlier.

  Tested on omap3evm at against latest master at:
  bd061a5 : Merge branch 'master' of git://git.denx.de/u-boot-sh

  To build successfully, make this substituion in board/ti/evm/evm.c:
  -#include <asm/arch/gpio.h>
  +#include <asm/omap_gpio.h>
  This problem was addressed in separate RFC. Patches
  will follow shortly. (Substituion is not real fix).
