[PATCH AUTOSEL 4.18 130/136] iio: 104-quad-8: Fix off-by-one error in register selection

[Sasha Levin]

From: William Breathitt Gray <vilhelm.gray@xxxxxxxxx>

[ Upstream commit 2873c3f0e2bd12a7612e905c920c058855f4072a ]

The reset flags operation is selected by bit 2 in the "Reset and Load
Signals Decoders" register, not bit 1.

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