The following commit always reports positive value when Apple hardware
queries _OSI("Darwin"):

 Commit: 7bc5a2ba
 Subject: ACPI: Support _OSI("Darwin") correctly

However since this implementation places the judgement in runtime, it
breaks acpi_osi=!Darwin and cannot return unsupported for _OSI("WinXXX")
invoked before invoking _OSI("Darwin").

This patch fixes the issues by reverting the wrong support and implementing
the default behavior of _OSI("Darwin")/_OSI("WinXXX") on Apple hardware via
DMI matching.

Fixes: 7bc5a2ba (ACPI: Support _OSI("Darwin") correctly)
