dt-bindings: mfd: samsung,s2mps11: Split s2mpg10-pmic into separate file

The samsung,s2mpg10-pmic binding is going to acquire various additional
properties. To avoid making the common samsung,s2mps11 binding file too
complicated due to additional nesting, split s2mpg10 out into its own
file.

As a side-effect, the oneOf for the interrupts is not required anymore,
as the required: node is at the top-level now.

+description: |
+  This is part of the device tree bindings for the S2MPG family of Power
+  Management IC (PMIC).
+
+  The Samsung S2MPG10 is a Power Management IC for mobile applications with buck
+  converters, various LDOs, power meters, RTC, clock outputs, and additional
+  GPIO interfaces.
