Second round of IIO fixes for the 4.0 cycle (or round one part two really!)

These are fixes for patches in the recent merge window and are in a separate
 branch to avoid rebasing the main fixes-togreg branch.
 
 * jsa1212 - select missing REGMAP_I2C
 * ssp_common - build warning fix for PM functions when PM not in use.
 * ak8975 - the addition of a utility library for this driver (as part of
            adding new device support) led to a dependency not being inforced
 	   for the original driver (I2C and GPIOLIB).
