Since the migration to fwnode_get_name in commit 4f47a236a23d ("iio:
adc: qcom-spmi-adc5: convert to device properties") the resulting
adc5_channel_prop::channel_name (renamed from datasheet_name in the
previous patch) - which is propagated into iio_chan_spec::extend_name -
was containing the DT node name including @xx suffix if a "label"
property is not present, while adc5_channels::datasheet_name was thus
far set by the macros but always remained unread.  Put it to use instead
of using a confusing name containing @xx in sysfs filenames (again, when
"label" is not set).
