There is no device like Fw-cfg in Qemu in Cloud Hypervisor, so a specific Acpi handler is introduced here. The handler implemented here is in a very simple way: 1. acquire the RSDP from the PCD variable in the top ".dsc"; 2. get the XSDT address from RSDP structure; 3. get the ACPI tables following the XSDT structure and install them one by one; 4. get DSDT address from FADT and install DSDT table.
