ARM: dts: msm: Add gcc qcom-dummycc support for TVM on sun

For upstream and tvm qup common driver uses gcc phandles which
are common in dt and to avoid qup driver probe failure qcom-dummycc
is added as they are nop. This helps in avoiding additional logic
in qup driver to not conditionalize based on variant.
