[PATCH v6] dt-bindings: regulators: convert non-smd RPM Regulators bindings to dt-schema

[Neil Armstrong <neil.armstrong@linaro.org>]

Convert the non-SMD Regulators bindings to dt-schema, the old text based
bindings will be deleted later since the RPM bindings are not yet converted.

This is a second round of bindings & DT fixes for the MDM9615 platform.

This second round focuses on less trivial changes like pinctrl & regulators bindings,
the remaining work will mainly be fixing the qcom,kpss-timer/qcom,msm-timer situation and
add bindings for qcom,lcc-mdm9615, qcom,kpss-gcc & swir,mangoh-iotport-spi.

Dependencies: None

+description:
+  The Qualcomm RPM regulator is modelled as a subdevice of the RPM.
+
+  Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,rpm.yaml
+  for information regarding the RPM node.
+
+  The regulator node houses sub-nodes for each regulator within the device.
+  Each sub-node is identified using the node's name, with valid values listed
+  for each of the pmics below.
