Subject: [PATCH v5 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.

Changes in v5:
- Remove Fixes tag
- redefine acpi_get_physical_device_location() to return bool
- Link to v4: https://lore.kernel.org/r/20241211-fix-ipu-v4-0-4102e97aceb6@chromium.org

Changes in v4 (Thanks Sakari & Mauro):
- Squash the two ipu changes and merge everything via ACPI
- Space after ;
- move acpi_device_handle to avoid fwd declaration.
- Link to v3: https://lore.kernel.org/r/20241210-fix-ipu-v3-0-00e409c84a6c@chromium.org

Changes in v3:
- Prefer static inlines to macros (Thanks Rafael).
- Link to v2: https://lore.kernel.org/r/20241122-fix-ipu-v2-0-bba65856e9ff@chromium.org

Changes in v2:
- Add helpers in acpi to avoid conditional compilation
- Link to v1: https://lore.kernel.org/r/20241122-fix-ipu-v1-1-246e254cb77c@chromium.org
