soc/amd/picasso/fsp_params: add asserts for descriptor count
With the updated FSP UPD headers there are enough DXIO descriptor slots in the UPD, so we can now add asserts to make sure that the mainboard doesn't pass more DXIO/DDI descriptors than the UPD has slots for. This is part of the DXIO/DDI descriptor handling cleanup.
