[PATCH v2 1/2] dt-bindings: regulator: add PF0900 regulator yaml

[Joy Zou <joy.zou@nxp.com>]

Add device binding doc for PF0900 PMIC driver.

Signed-off-by: Joy Zou <joy.zou@nxp.com>
---
Changes for v2:
1. modify the binding file name to match compatible string.
2. add one space for dt_binding_check warning.
3. remove unnecessary quotes from "VAON".
4. remove the unnecessary empty line.
5. move unevaluatedProperties after the $ref.
6. move additionalProperties after regulator type.
7. remove unnecessary regulator description

+
+description:
+  The PF0900 is a power management integrated circuit (PMIC) optimized
+  for high performance i.MX9x based applications. It features five high
+  efficiency buck converters, three linear and one vaon regulators. It
+  provides low quiescent current in Standby and low power off Modes.
