Subject: [PATCH 2/5] staging: iio: adc: ad7816: Rename state structure

Rename the main driver state structure from 'ad7816_chip_info' to
'ad7816_state' to avoid confusion with the upcoming structure that will
hold static, per-device-type information.

This is purely a mechanical rename with no functional changes.
