Series ipu6: get rid of all the IS_ENABLED(CONFIG_ACPI) | expand

Commit Message

Ricardo Ribalda Nov. 22, 2024, 9:48 a.m. UTC 
The ACPI headers have introduced implementations for some of their
functions when the kernel is not configured with ACPI.

Let's use them instead of our conditional compilation. It is easier to
maintain and less prone to errors.
