Subject: [PATCH 04/16] iio: adc: max1027: Lower conversion time

When only a few channels are requested, the core will request all of
them as long as ->available_scan_masks is present, thus reducing the
impact of any driver side optimization to avoid converting the unneeded
channels.

Do not share this bitmap with the core, which is optional anyway.
