iio: xilinx-ams: Don't include ams_ctrl_channels in scan_mask

Browse source

[ Upstream commit 89b898c627 ]

ams_enable_channel_sequence constructs a "scan_mask" for all the PS and
PL channels. This works out fine, since scan_index for these channels is
less than 64. However, it also includes the ams_ctrl_channels, where
scan_index is greater than 64, triggering undefined behavior. Since we
don't need these channels anyway, just exclude them.
