Not using board revision is causing confusion about which board is
supported and tested. Mark dts files exactly with board revision which
was tested. When new board revision arives it can be symlink if SW view
is the same. Also add -revX suffix to compatible string because user space
tools are parsing this string and can change behavior depends of board

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.
