xen: features and fixes for 4.8-rc0

- - ACPI support for guests on ARM platforms.
- - Generic steal time support for arm and x86.
- - Support cases where kernel cpu is not Xen VCPU number (e.g., if
  in-guest kexec is used).
- - Use the system workqueue instead of a custom workqueue in various
  places.

Thanks.

David
