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

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