ACPI / osi: Fix default _OSI(Darwin) support
The following commit always reports positive value when Apple hardware
queries _OSI("Darwin"):
Commit: 7bc5a2bad0b8d9d1ac9f7b8b33150e4ddf197334
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: 7bc5a2bad0b8 (ACPI: Support _OSI("Darwin") correctly)
