1) move a generic helper function out of ring_sw. It applies to other buffers as well.
2) Get rid of a lot of left over function definitions.
3) Move all the access functions into static structures.
4) Introduce and use a static structure for the setup functions, preenable etc.
Some driver conversions thanks to Michael Hennerich (pulled out of patches
that would otherwise sit after this).

until the rewrite in the previous patch (and hence didn't work).

Change suggested by Arnd Bergmann, Related patch to remove
pointless (now) dead_offset parameter will have await
proper fix for the sca3000 driver. That depends on
some intermediate patches so may be a little while.
