Subject: [PATCH v1 1/7] regulator: dt-bindings: add documentation for s2mps16-pmic regulators

The S2MPS16 is a PMIC found in exynos8890 devices, which controls voltage
regulators - 38 LDOs, of which 11 are used for CP, and 11 BUCKs, of which
1 is used for CP. Provide documentation for devicetree definitions,
regulator naming patterns, etc.
