[PATCH v3 05/20] dt-bindings: mfd: samsung,s2mpg10: Link s2mpg10-pmic to its regulators

["André Draszik" <andre.draszik@linaro.org>]

Update the regulators node to link to the correct and expected
samsung,s2mpg10-pmic regulators binding, in order 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 changes are done within an allOf: / if: match, because the
intention is to add the S2MPG11 PMIC to this binding as well, and doing
it this way avoids additional churn in those follow-up patches.
