tpci200_slot_map_space() should return 0 if the operation was properly

It should return the same value given by the match function of the ipack_driver
that has been called.
Returning 0 here, means that the match has failed and it could be succeed.

The IIO DAC drivers are in a reasonably good shape. They all make use of channel
spec and non of them provides non-documented sysfs attributes. Code style should
be OK as well, both checkpatch and coccicheck only report trivial issues.
So lets move the whole folder out of staging.

The header for this driver contains some private structs and defines, which do
not have to be shared between multiple source files, as well as the platform
data struct for this driver, which has to be shared with other source files.
Since there is no need to expose those private structs and defines move them to
the source file.

Convert the max517 driver to channel spec. As part of the conversion the
"out_voltage_1&2_raw" property, which updates both channel 1 and 2
simultaneously with the same value, is lost, since this is not really covered by
the IIO spec and has only a limited use case in practice.
Also the channel index for the sysfs files is now zero based instead of one
based, which means all channel numbers will be lower by one. E.g.
"out_voltage_1_scale" instead of "out_voltage_2_scale"

We often have the case were we do have a enum style channel attribute. These
attributes have in common that they are a list of string values which usually
map in a 1-to-1 fashion to integer values.
This patch implements some common helper code for implementing enum style
channel attributes using extended channel attributes. The helper functions take
care of converting between the string and integer values, as well providing a
function for "_available" attributes which list all available enum items.

Add sub-driver for the ambient-light-sensor interface on National
Semiconductor / TI LM3533 lighting power chips.
The sensor interface can be used to control the LEDs and backlights of
the chip through defining five light zones and three sets of
corresponding output-current values.
The driver provides raw and mean adc readings along with the current
light zone through sysfs. A threshold event can be generated on zone
changes. The ALS-control output values can be set per zone for the three
current output channels.
