kirkwood: switch to kernel 4.9
Add patches-4.9, some of them (heavily) rewritten:
- ea4500 is upstream available, keep only LEDE changes in dts
- ea3500 is changed to match the structure of the upstream ea4500 dts
- nsa310s rewritten to include the common dtsi
- nsa325 is dropped, since already upstream

[refresh kernel config, add on100, use the switchdev based mv88e6171
driver for the linksys boards, keep lede specific rootfs/kernel
partition names for linksys boards, reorder patches]
