* SMCInvoke driver to provide transport between TZ and Linux

Required properties:
- compatible : Should be "qcom,smcinvoke"
- qcom,support-legacy_smc : indicates that secure side uses QCOM_SCM_SMCINVOKE_INVOKE_LEGACY (value = 0x00) for smcinvoke
			    functionality.

Example:
	qcom_smcinvoke: smcinvoke@87900000 {
		compatible = "qcom,smcinvoke";
	};

Example: For targets where secure side runs with QCOM_SCM_SMCINVOKE_INVOKE_LEGACY cmd id
	qcom_smcinvoke: smcinvoke@87900000 {
                compatible = "qcom,smcinvoke";
		qcom,support-legacy_smc;
        };
