Zide Chen 865ee2956e hv: emulate ACPI reset register for Service OS guest
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.
