soc/amd/picasso: don't apply unconfigured USB2 PHY tune parameters

Since FSP pre-populates the UPD struct with the non-zero default values,
coreboot shouldn't set them to zero in the case that they aren't
configured in the board's devicetree. Since all parameters being zero is
a valid case, this patch adds another devicetree option that applying
the devicetree settings for the USB2 PHY tuning depends on being set.

BUG=b:161923068
