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.
