Subject: [PATCH v4 5/6] dt-bindings: mailbox: qcom: set correct #clock-cells

IPQ6018 and IPQ8074 require #clock-cells to be set to 1 as their APSS
clock driver provides multiple clock outputs.

So allow setting 1 as #clock-cells and check that its set to 1 for IPQ6018
and IPQ8074, check others for 0 as its currently.
