Subject: [PATCH v3 2/6] dt-bindings: usb: qcom,pmic-typec: add support for
 the PMI632 block

The PMI632 PMIC has the same Type-C register block as the PM8150B.
However this PMIC doesn't support USB Power Delivery. As such it doesn't
have the second region used by the existing pm8150b bindings. Add if
clauses to handle the PMI632 usecase.
