Not always a ring so naming is missleading.
Also, kfifo_buf is probably first buffer to take out of staging and it
definitely isn't a ring.

The scan mask will be dynamically assigned in register, so don't
use it before that.
In adis16260 I've moved it as I know this driver has userspace code.
Same for sca3000 where it is cost free due to hardware buffer.
Can do that for the others, but in theory userspace code should always
have been checking these and setting them appropriately anyway!
V2: Clear default mask out of adis16400 as reported by Michael

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).

For clean drivers its easier to convert to chan_spec based
registration than to work around the scan_el attributes
going away.
Some minor cleanups done whilst here.
Untested.
V3: rebase fixup and make attribute_group static.
V2: IIO_CHAN macro updates.

The job this was intended to do (never implemented) is now done
by explicit definition of _type attributes in all drivers

These drivers use kzalloc() but don't include slab.h. They currently
build though because the spi.h header will pull in slab.h for us. But
rather than rely on that behavior forever, include slab.h explicitly.
