nb/amd/pi/00730F01/northbridge: drop nodeid from get_dram_base_limit
This APU is always a single-node and also only has one DRAM controller,
so there is only one valid DRAM base and limit register. It's also worth
mentioning that the assumption made in get_dram_base_limit that the n-th
node is using the n-tn DRAM range register was valid for K8, but not
necessarily on newer generations than that.
TEST=PC Engines APU2 still boots and doesn't show any new problems
