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: simplify tx ring index handling
-
-Keep incrementing ring->start and ring->end instead of pointing it to
-the actual ring slot entry. This simplifies the calculation of the
-number of free slots.
