The only way this driver can be probed by MFD via its parent device.

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

 drivers/spi/spi-at91-usart.c:684:34: warning: ‘at91_usart_spi_dt_ids’ defined but not used [-Wunused-const-variable=]
 684 | static const struct of_device_id at91_usart_spi_dt_ids[] = {
