soc/amd/picasso/soc_util: rework reduced I/O chip detection

Both Dali and Pollock chips have less PCIe, USB3 and DisplayPort
connectivity. While Dali can either be fused-down PCO or RV2 silicon,
Pollock is always RV2 silicon.

Since we have all boards using this code in tree right now,
soc_is_dali() can be renamed and generalized to soc_is_reduced_io_sku().
