We want to be able to compile_test the ipu6 driver in situations with
!ACPI.

In order to do this we had to add some conditional #ifs, which lead to
false positives on the static analysers.

Let's implement some helpers when !ACPI in the acpi headers to make the
code more easier to maintain.

We can land the first patch of this series ASAP to fix the current
smatch warning.

Not needed, as patch 7 will revert it.

patches 2-6 look ok to me, but I'll leave it to ACPI maintainers
to review. From my side:

See my review with my R-B.

As the crucial changes are at ACPI side, I'm assuming that this will
be merged via ACPI tree.
