staging driver fixes for 3.13-rc3 

Here are some bugfixes for the staging and IIO drivers for 3.13-rc3.
 
 The resolve the vm memory issue in the tidspbridge driver, fix a much-reported
 build failure in an ARM driver, and some other IIO bugfixes that have been
 reported.

Since logical minimum is still set 0 instead of 1,
there is no easy way to differentiate.
