soc/intel/xeon_sp/spr: Add soc_config_iio to set IIO UPD from mainboard

To deduplicate mainboard mainboard_config_iio since there are a few
SPR-SP mainboards now.

The flow would be soc function initialize_iio_upd initializes the table
with the default values which are mostly zero, then mainboard can
overwrite it by soc_config_iio.
