Maybe we can start dropping this, since kernel is now able to get
bootargs from atags even in case that bootloader can not pass dtb

Do we still have no way to figure the mac address from hardware setup
(fuse or something) on sabrelite board?

Nit: If you want to comment it, please comment it in the consistent way,
which is '/* GPIO3_23 */'.
