* SMCInvoke driver to provide transport between TZ and Linux

Required properties:
- compatible : Should be "qcom,smcinvoke"
- reg : should contain memory region address reserved for loading secure apps.
- qcom, msm_bus,name: Should be "smcinvoke-noc"
- qcom, msm_bus,num_cases: Depends on the use cases for bus scaling
- qcom, msm_bus,num_paths: The paths for source and destination ports
- qcom, msm_bus,vectors: Vectors for bus topology.
- qcom,ce-opp-freq: indicates the CE operating frequency in Hz, changes from target to target.
  - qcom,clock-support : indicates clocks are handled by smcinvoke (could be handled by RPM)

Example:
        qcom_smcinvoke: smcinvoke@88000000 {
                compatible = "qcom,smcinvoke";
                reg = <0x88000000 0x500000>;
                qcom,clock-support;
                qcom,msm-bus,name = "smcinvoke-noc";
                qcom,msm-bus,num-cases = <4>;
                qcom,msm-bus,num-paths = <1>;
                qcom,msm-bus,vectors-KBps =

                                <47 512 393600 3936000>;
                clocks = <&clock_gcc clk_crypto_clk_src>,

                        <&clock_gcc clk_gcc_crypto_axi_clk>;
                clock-names = "core_clk_src", "core_clk",
                                "iface_clk", "bus_clk";
                qcom,ce-opp-freq = <100000000>;
