[PATCH] ARM: sunxi: dt: add EMAC aliases

[Emilio López]

U-Boot uses the ethernet0 alias to locate the right node to fill in
the MAC address of the first ethernet interface. This patch adds the
alias on all the sunxi boards with EMAC and an ethernet port. In this
way, people using ethernet in U-Boot (eg, for tftp) can keep a consistent
address on both U-Boot and Linux with no additional effort.

Hi everyone,

I have tested this on a cubieboard2 and found it to work as intended, 
and I don't see why it wouldn't work on the other boards, given that 
the U-Boot codebase is shared. It may be worth submitting this for 
3.13-rc0, but I'm not the one that has to make that call :)

Cheers,

Emilio
