[PATCH] mfd: kempld-core: Mark kempld-acpi_table as __maybe_unused

[Michael Brunner]

The Intel 0-DAY CI Kernel Test Service reports an unused variable
warning when compiling with clang for PowerPC:

>> drivers/mfd/kempld-core.c:556:36: warning: unused variable 'kempld_acpi_table' [-Wunused-const-variable]
   static const struct acpi_device_id kempld_acpi_table[] = {

The issue can be fixed by marking kempld_acpi_table as __maybe_unused.

Fixes: e8299c7313af ("[PATCH] mfd: Add ACPI support to Kontron PLD driver")
