Subject: [PATCH 1/6] dt-bindings: regulator: qcom,spmi-regulator: Convert to dtschema

Convert the bindings of Qualcomm SPMI regulators to DT schema.

Signed-off-by: Robert Marko <robimarko@gmail.com>

I am aware that syscon alone is not really acceptable, its converted
directly from the old text bindings.

There is also the issue of some MSM8994, MSM8996 and APQ8096 devices using
'#address-cells', '#size-cells', some even defining reg property for
regulators.

Any advice on how to solve these issues is appreciated.
