This adds support for the Olimex A20-OLinuXino-Lime2
https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2
Differences to previous Lime boards are 1GB RAM and gigabit ethernet

I'd like to see this go in with the dual license, but not really
sure if that's appropriate while sunxi-common-regulators.dtsi is still
GPL only. Happy to resend with single license header if it's deemed
better for now though.
