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.
