[PATCH 1/9] iio: adc: exynos_adc: use regmap to retrieve struct device

[Alison Schofield <amsfield22@xxxxxxxxx>]

Driver includes struct regmap and struct device in its global data.
Remove the struct device and use regmap API to retrieve device info.

Patch created using Coccinelle plus manual edits.
