[PATCH v2 14/14] spi: spi-amd: Do not define 'struct acpi_device_id' when !CONFIG_ACPI

[Lee Jones]

Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI,
struct 'spi_acpi_match' becomes defined but unused.

Fixes the following W=1 kernel build warning(s):

 drivers/spi/spi-amd.c:297:36: warning: âspi_acpi_matchâ defined but not used [-Wunused-const-variable=]
 297 | static const struct acpi_device_id spi_acpi_match[] = {
 | ^~~~~~~~~~~~~~
