Subject: [PATCH 04/17] dt-bindings: mfd: samsung,s2mps11: add s2mpg10-pmic
 regulators

Add a regulators node to the s2mpg10-pmic to describe the regulators
available on this PMIC.

Additionally, describe the supply inputs of the regulator rails, with
the supply names matching the datasheet.

Note 1: S2MPG10 is typically used as the main-PMIC together with an
S2MPG11 PMIC in a main/sub configuration, hence the datasheet and the
binding both suffix the supplies with an 'm'.

Note 2: The binding needs to switch from 'additionalProperties' to
'unevaluatedProperties', to allow adding the specific -supply
properties for S2MPG10 only, as otherwise we'd have to resort to a
global wildcard with negating inside each of the compatible matches.
