[PATCH v2 0/4] amr64: dts: exynos: add dedicated SYSREG compatibles to Exynos850 and Exynosautov9

[Sriranjani P]

Exynos850 and Exynosautov9 has several different SYSREGs, so use dedicated
compatibles for them in dtsi file and add respective compatible in the
samsung exynos devicetree binding document.

Changes since v1:
1. As per Krzysztof comment made an enum of deprecated compatibles.
