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. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

-Subject: [PATCH] spi: Check to see if the device is processing a message
- before we idle
-
-cur_msg is updated under the queue lock and holds the message we are
-currently processing. Since currently we only ever do removals in the
-pump kthread it doesn't matter in what order we do things but we want
-to be able to push things out from the submitting thread so pull the
-check to see if we're currently handling a message before we check to
-see if the queue is idle.
