Second round of IIO new stuff and cleanups for the 3.11 cycle.

1) Pressure sensor support in the st sensors driver - LPS331AP currently.
2) Graduation of generic interrupt from staging with some related cleanup.
3) A number of platform_set_drvdata on remove removals.
4) 2 conditional build changes to prevent device tree structures from being
   built in when device tree isn't enabled.  These just save a bit of space
   rather than being strictly required at the moment.
5) A couple of strict_strtoul -> kstrtoul conversions.
