[LEDE-DEV] [PATCH v2] ramips: build factory images for Buffalo WSR-1166DHP/WSR-1166DHP2

factory image has to have custom trx magic, and trx file will be written
in the middle of the mtd3 partition (bootpartition=1 on u-boot).
therefore, sysupgrade.bin cannot be installed directly from stock Web UI.
with this patch, factory.bin will be built with initramfs image which
can be installed from stock Web UI, and can be used to install
sysupgrade.bin.
install procedure:
1. install initramfs image (factory.bin) from stock Web UI
2. ssh root at 192.168.1.1
3. run "mtd erase firmware" (erase factory.bin in mtd3)
4. install sysupgrade.bin by sysupgrade
