iio: ti_am335x_adc: Fix: Use same step id at FIFOs both ends
commit baa3c65298c089a9014b4e523a14ec2885cca1bc upstream.
Since AI lines could be selected at will (linux-3.11) the sending
and receiving ends of the FIFO does not agree about what step is used
for a line. It only works if the last lines are used, like 5,6,7,
and fails if ie 2,4,6 is selected in DT.
