Which tree is this based on? I cant see the existing isslave property in
mainline HEAD (commit 29fbff8698fc0ac1).

This ifdef is broken. At least for arm64, a single kernel image can be
booted with either ACPI or DT. We need separate accessors for DT and
ACPI to handle these differently, or you need to explicitly check
whether or not you have ACPI or DT at runtime.

Thanks,
Mark.
