Handle the PIO reset register that is defined in host ACPI: Parse host FADT table to get the host reset register info, and emulate it for Service OS: - return all '1' for guest reads because the read behavior is not defined in ACPI. - ignore guest writes with the reset value to stop it from resetting host; if guest writes other values, passthru it to hardware in case the reset register supports other functionalities.
