Subject: [PATCH 0/4] iio: exynos-adc: use syscon instead of ioremap

This patch does the following
1. Use the syscon and Regmap API instead of ioremappaing the
   ADC_PHY register from PMU.
2. Moves the exynos-adc.txt from bindings/arm/samsung/
   to bindings/iio/adc/.
3. Updates the Documentation in exynos-adc.txt with syscon phandle
   for the ADC nodes.
4. Updates the Dts files for Exynos3250, Exynos4x12, Exynos5250,
   Exynos5420 with the syscon phandle.

Tested on Exynos5420 based Peach PIT and Exynos5800 based Peach PI
by verifying sysfs entries provided by HWMON based NTC thermistors.

Tested-By for Exynos3250, Exynos4x12 would be appreciated.
