As a precursor to splitting buffer.h, lets make sure all drivers
include the relevant headers rather than relying on picking them
up from kfifo_buf.h.

Check for iio_info structures that are only stored in the info field of a
iio_dev structure.  This field is declared const, so iio_info structures
that have this property can be declared as const also.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r disable optional_qualifier@
identifier i;
position p;
@@
static struct iio_info i@p = { ... };

@ok@
identifier r.i;
struct iio_dev e;
position p;
@@
e.info = &i@p;

@bad@
position p != {r.p,ok.p};
identifier r.i;
struct iio_info e;
@@
e@i@p

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
 struct iio_info i = { ... };
// </smpl>

The result of size on this file before the change is:

and after the change it is:

This patch adds accelerometer iio driver which uses sensorhub as data
provider.
