Subject: [PATCH v3 0/7] ipu6: get rid of all the IS_ENABLED(CONFIG_ACPI)

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.
