iio: 104-quad-8: Fix index control configuration

Browse Source 
The LS7266R1 requires bits 5 & 6 to be high in order to select the Index
Control Register. This patch fixes a typo that incorrectly selects the
Input/Output Control Register where the Index Control Register was
desired.

Fixes: 28e5d3bb0325 ("iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8")
