[OpenWrt-Devel] ramips: Add support for Netgear EX2700

This patch adds support for the Netgear EX2700 and builds an approriate 
sysupgrade image. 

What's missing is the option to build a factory image flashable via the 
router's stock web interface, but this approach is hindered by the fact 
that u-boot operforms an additional integrity check, which expects a 
uImage header in the last 64 bytes of the "kernel" partition, which
the bootloader expects to be 960k, a size exceeded by the standard 
OpenWrt kernel.

please stick to the alphabetical ordering (there are 2 more cases like
this later on in the patch. please fix all 3 and resend the patch

rest looks good
