Second round of IIO fixes for the 3.13 cycle.

Browse source 
2 fixes here.
 
 * The gp2ap020a00f is a simple missing kconfig dependency.
 
 * The hid sensors hub fix is a work around for an issue introduced by hardware
 changes due to a certain large software vendor having an 'interesting'
 interpretation of the specification and hence indexing some arrays from 1
 rather than 0.  The fix takes advantage of the logical min and max reading
 facilities introduced by the precursor patch to figure out whether we have
 a 0 indexed or 1 indexed device and to adjust appropriately.  It also
 drops a previous kconfig option that allowed this issue to be worked around
 at build time.
