ramips: build factory images for Netgear EX2700
This patch adds support for building factory and sysupgrade images
for the Netgear EX2700 that don't require modification of u-boot
environment variables.
The bootloader on this device expects the kernel partition to end
on a 64k block boundary. The last 64 byte of the kernel partition
must contain a valid uImage header - in the stock firmware, this is
the uImage header of the root filesystem. For this patch, we're using
the uImage header of a 0 byte partition (ex2700-fakeroot.uImage).
