gcc-15: acpi: sprinkle random '__nonstring' crumbles around

This is not great: I'd much rather introduce a typedef that is a "ACPI
name byte buffer", and use that to mark these special 4-byte ACPI names
that do not use NUL termination.

But as noted in the previous commit ("gcc-15: make 'unterminated string
initialization' just a warning") gcc doesn't actually seem to support
that notion, so instead you have to just mark every single array
declaration individually.

So this is not pretty, but this gets rid of the bulk of the annoying
warnings during an allmodconfig build for me.
