Add Intel Edison board which is using U-Boot.

In case we're building for Intel Edison, we must have 4096 bytes of zeroes in the beginning on u-boot.bin. This is done in board/intel/edison/config.mk.
First run sets hardware_id environment variable which is read from System Controller Unit (SCU).
Serial number (serial# environment variable) is generated based on eMMC CID.
MAC address on USB network interface is unique to the board but kept the same all over the time.
Set mac address from U-Boot using following scheme: OUI = 02:00:86 next 3 bytes of MAC address set from eMMC serial number
This allows to have a unique mac address across reboot and flashing.
