Subject: [PATCH] dt-bindings: pinctrl: qcom,pmic-mpp: clean up example

The Multi-Purpose Pin controller block is part of an SPMI PMIC (which in
turns sits on an SPMI bus) and uses a single value for the register
property that corresponds to its base address.

Clean up the example by adding a parent PMIC node with proper
'#address-cells' and '#size-cells' properties, dropping the incorrect
second register value, adding some newline separators and increasing the
indentation to four spaces.
