[PATCH v3 06/20] dt-bindings: mfd: samsung,s2mpg10: Add s2mpg11-pmic

[André Draszik]

The Samsung S2MPG11 PMIC is similar to the existing S2MPG10 PMIC
supported by this binding.

It is a Power Management IC for mobile applications with buck
converters, various LDOs, power meters, NTC thermistor inputs, and
additional GPIO interfaces and typically complements an S2MPG10 PMIC in
a main/sub configuration as the sub-PMIC.

Like S2MPG10, communication is via the Samsung ACPM firmware and it
therefore needs to be a child of the ACPM firmware node.

Add the PMIC, the regulators node, and the supply inputs of the
regulator rails, with the supply names matching the datasheet.

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

v3:
- move to new samsung,s2mpg10.yaml file
- deny 'clocks' property
- mention NTC thermistor inputs in commit message
- move all patternProperties to top-level

v2:
- add | to vinb*-supply description for better formatting to mark as
  literal style
- mention GPIOs in commit message
