Second set of IIO rework and new drivers for the 3.7 cycle.

Firstly we have the second half of a series reworking support for
the various sigma delta ADCs from Analog.  The first half was fixes
that have already merged in the v3.6 cycle.  Other than some
little cleanups this mainly consists of a unifying library module
that the various drivers can then use.  Another new driver is
using this undergoing revisions and the code reduction already
seen from this is considerable.  A nice piece of work.

Secondly we have a good number of tidying up patches from various
sources doing things like adding include guards and removing
unintended header ordering requirements.  Also a mass annotation
of missing __devinit/exit.  Peter Meerwald has been getting around
with cleanup of lis3l02dq, documentation fixes, white space clenaups
and a small issue with my spelling ;)

Thirdly we have some improvements to our kfifo usage that have
been around for a while but are now suddenly in demand from a
number of users.

Forth we have some clk_prepare_enable and clk_prepare_disable
cleanups.

Fifth is the addition of i2c dacs to the ad5446 driver

Finally we have some email address updates. I'll do the
MAINTAINERS one separately.

So a general mixed bag but nothing terribly controversial
or 'exciting'.

staging: comedi: das08: Remove pc104 bustype value

Remove the `pc104` value from `enum das08_bustype` and replace
occurrences of it in the code and data with the `isa` value.  The code
treats them as equivalent anyway with expressions like
`(thisboard->bustype == isa || thisboard->bustype == pc104)`.

The description of the A/D LSB register at offset 0 seems incorrect in

staging: comedi: adv_pci_dio: simplify the 'detach'

Currently the 'detach' function in this driver walks thru the
boardinfo in order to find the subdevice index for any sdio
subdevices in order to call the subdev_8255_cleanup(). Then
it goes thru all the subdevices to clean the s->private pointer.

All the sdio subdevices are unique in that the s->type is
COMEDI_SUBD_DIO. Use that to know when to call the cleanup
for the 8255 subdevice.
