[tf-rmm] Does the confidential virtual machine support hot-plug for CPU, memory, and devices？

Cloud vendors hope that cloud servers have hot-plug capabilities for CPU, memory, and devices. In confidential virtual machine scenarios, the measurement values ​​will change after hot-plug , and rmi_data_create needs to be called to dynamically update the device tree information. Please consult CCA's plan for the hot-plug capability , and under the security model of confidential virtual machines, should the hot-plug capability of confidential virtual machines be supported?
