ACPICA: Add support to externally execute _OSI method

Browse Source 
The current implemenation of _OSI within ACPICA only allows other
control methods to execute _OSI. This change allows the host
OS to execute _OSI via the AcpiEvaluateObject interface. _OSI
is a special method -- it does not exist in the AML code, it is
implemented within ACPICA.
