Subject: [PATCH 09/10] gpio: gpio-mlxbf2: Tell the compiler that ACPI functions may not be use

... as is the case when !CONFIG_ACPI.

Fixes the following W=1 kernel build warning:

drivers/gpio/gpio-mlxbf2.c:312:36: warning: ‘mlxbf2_gpio_acpi_match’ defined but not used [-Wunused-const-variable=]
312 | static const struct acpi_device_id mlxbf2_gpio_acpi_match[] = { | ^~~~~~~~~~~~~~~~~~~~~~
