The point is to be able to share some information with the guest without the need for emulating devices that would be present on real hardware. Since Cloud Hypervisor supports loading a PVH ELF binary, the CloudHv target is updated to be generated as such. Relying on the PVH boot specification, we don't need to hardcode the location of the ACPI tables anymore since we can retrieve the RSDP address from the hvm_start_info structure. Same thing for the RAM below 4G, we can find this information through the PVH memmap entries rather than relying on the emulated CMOS.
