dt-bindings: pinctrl: qcom,pmic-mpp: Fix schema for "qcom,paired"

The "qcom,paired" schema is all wrong. First, it's a list rather than an
object(dictionary). Second, it is missing a required type. The meta-schema
normally catches this, but schemas under "$defs" was not getting checked.
A fix for that is pending.
