From: Al Stone <al.stone@xxxxxxxxxx>
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.

Hi Al, remove PREFIX here and use pr_fmt() instead as
I mentioned in previous patch :)
Thanks
