Subject: [PATCH 1/2] ACPICA: expose OSI version

Expose acpi_gbl_osi_data so that driver can know the value of the last
successfull call of _OSI. The definitions for OSI versions have been
moved to actypes.h so that other components can access them.

Based on a patch by Matthew Garrett <matthew.garrett@...ula.com>, which
is again based on a patch by Seth Forshee <seth.forshee@...onical.com>.
