The application is now considerably more generic and should cope
with all devices in tree. The process function will need to be
extended to handle other type values as needed.

The combined orientations allow handling of typical motion and free fall
detectors to be handled as threshold events just applied to a number of
axes via boolean operations. So freefall is when x, y and z magnitudes
are all below a threshold for a particular period. Motion detectors
are typically whether x or y or z are above a particular value.

adding support for the ISL 29018 ambient light and proximity sensor.
Addressed comments from reviews by Jonathan Cameron and Joe Perches
* Removed some excess dbg prints that only printed function name
* Renamed some properties to make them more descriptive
* Added a property to list available adc resolutions
* Defined arrays for resolutions/ranges as static const
* Change loops initialization to memset for extensibility.
* used sizeof() instead of ARRAY_SIZE() to be safer
* Added a property to list available adc ranges
* Fixed warnings and property names.

-drop in_precision in favor of new in_type -
This also fixes the bug from the scan elements move (as a side effect)
-add sign and storagebits to struct ad799x_chip_info
-properly mask the results based on ad799x_chip_info:bits
staging: iio: adc: ad799x misc fixed per iio list review
remove new line
remove storagebits from struct ad799x_chip_info
use defined storagebits value for in_type

The device found passed to the attr functions is that of the ring
buffer, not the the iio_dev so we need to bounce through one more
hop to get the right address.

As Manuel Stahl observed, putting data into the naming of an attribute
(beyond what it is for) breaks the one value per attribute rule (in spirit
at least). Hence we introduce a separate _index attribute for each scan
element to tell userspace the ordering in output from the buffer.
This will generate a lot of sparse warnings as all drivers will have unused
iio_const_attrs created. The rest of the set will clean these up.
The final patch will remove the old indexing method. It is not here so
as to maintain one or other interface for all devices as this set
progresses.
