TI LMU LM363x regulator device tree bindings

LM363x regulator driver supports LM3631 and LM3632.
LM3631 has five regulators and LM3632 supports three regulators.

Required property:
  - compatible: "ti,lm363x-regulator"

Optional properties:
  LM3632 has external enable pins for two LDOs.
  - enable-gpios: Two GPIO specifiers for Vpos and Vneg control pins.
                  The first entry is Vpos, the second is Vneg enable pin.

Child nodes:
  LM3631
  - vboost
  - vcont
  - voref
  - vpos
  - vneg

  LM3632
  - vboost
  - vpos
  - vneg

  Optional properties of a child node:
  Each sub-node should contain the constraints and initialization.
  Please refer to [1].

Examples: Please refer to ti-lmu dt-bindings [2].
