When building kernels without ACPI support the table is declared
but is not used because ACPI_PTR() turns it into a NULL.
Add the __maybe_unused attribute to stop the compiler whining.

Applied to the togreg branch of iio.git which is initially pushed out as testing
to let 0-day poke at it and see if we missed anything.
Thanks,
