Subject: ACPI: Add top-level ASL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Objects that are created with acpigen need to be declared
with External () for the generation of dsdt.asl to pass
iasl without errors.

There are some objects that are common to all platforms,
and some that should be declared only conditionally.
Having a top-level ASL helps to achieve this.
