ACPICA: expose OSI version
Expose acpi_gbl_osi_data so that code outside of ACPICA can check the value of the last successfull _OSI call. The definitions for OSI versions are moved to actypes.h so that other components can access them too. Based on a patch from Matthew Garrett which in turn was based on an earlier patch from Seth Forshee. [rjw: Changelog] Signed-off-by: Aaron Lu <aaron.lu@intel.com> Signed-off-by: Rafael J.
