Subject: [PATCH 5.17 0035/1126] iio: adc: xilinx-ams: Fixed wrong sequencer register settings

From: Robert Hancock <robert.hancock@...ian.com>

commit d5d786fb531697be74c567b3844c6897ddf1ffdd upstream.

Register settings used for the sequencer configuration register
were incorrect, causing some inputs to not be read properly.
