The VCPU stall detection mechanism allows to configure the expiration duration and the internal counter clock frequency measured in Hz. Add these properties in the schema. While this is a memory mapped virtual device, it is expected to be loaded when the DT contains the compatible: "qemu,vcpu-stall-detector" node. In a protected VM we trust the generated DT nodes and we don't rely on the host to present the hardware peripherals.
