In order to deprecate the use of _OSI for arm64 or other new architectures,
we need to make the default handler something we can change for various
platforms.  This patch moves the definition of acpi_osi_handler() -- the
function used by ACPICA as a callback for evaluating _OSI -- into a separate
file.  Subsequent patches will change which files get built so that we can
then build the version of _OSI we need for a particular architecture.

There is no functional change.

Nit: The street address of the FSF is not really useful here.  What if they move? :-)

This was one of the things checkpatch complained about, understandably :).  It's
a direct cut'n'paste from osl.c.

I can clean these up in the new file; would it help to clean up osl.c (at least
from checkpatch's point of view), as long as I'm at it?
