Hi Bob, Lv,

As discussed with Lv on linux-acpi maillist, I prepared this
patch for review.

Please treat this patch as a fix for next ACPICA version and
linux kernel 4.2 material, because we still can not
use the newest ACPICA for linux when this enum is missing,
any comments are welcomed.

Thanks
Hanjun
