kernel: Remove support for kernel 3.18

No target is using kernel 3.18 anymore, remove all the generic
support for kernel 3.18.

The removed packages are depending on kernel 3.18 only and are not used on
any recent kernel.

-Subject: [PATCH] bgmac: leave interrupts disabled as long as there is work
- to do
-
-Always poll rx and tx during NAPI poll instead of relying on the status
-of the first interrupt. This prevents bgmac_poll from leaving unfinished
-work around until the next IRQ.
-In my tests this makes bridging/routing throughput under heavy load more
-stable and ensures that no new IRQs arrive as long as bgmac_poll uses up
-the entire budget.
