ipq806x: enable Linksys EA8500 eth1 interface

[CHKDSK88]

At this moment Linksys EA8500 uses only eth0.

This patch change switch registers, which allow to use eth1 as lan
and eth0 as wan. The method work with similar Linksys EA7500V1
and it work with EA8500.

I'd remove all the references to the RFT from the commit and only keep them in the PR title/comment/message.

Despite that: Enable->enable and simmilar->similar

Hi @CHKDSK88, this would be great news, since this is a pending issue from when I first ported this board, 4 years ago.
It's been a long time and I don't remember exactly, but at the time I have fondled with most registers with no luck ( lede-project/source#134 , lede-project/source#6 & some others). I vaguely recall that the default values for that register where the same as the one used by the stock Linksys firmware, but I'm not really sure.

Right now I don't have the dev environment to compile and test it, but I will give it a try at the first opportunity.
I would really like to see this fixed.

eth0 is my LAN
