ACPI / osi: Collect _OSI handling into one single file
_OSI handling code grows giant and it's time to move them into one file.
This patch collects all _OSI handling code into one single file.
So that we only have the following functions to be used externally:
early_acpi_osi_init(): Used by DMI detections;
acpi_osi_init(): Used to initialize OSI command line settings and install
Linux specific _OSI handler;
acpi_osi_setup(): The API that should be used by the external quirks.
acpi_osi_is_win8(): The API is used by the external drivers to determine
if BIOS supports Win8.
CONFIG_DMI is not useful as stub dmi_check_system() can make everything
stub because of strip.
No functional changes.
