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 Hanjun
