Allow for configuration of FSP UPD from the device tree which will
override any settings which the FSP was built with itself.

Modify the MinnowMax and BayleyBay boards to transfer sensible UPD
settings from the Intel FSPv4 Gold release to the respective dts files,
with the condition that the memory-down parameters for MinnowMax are
also used.

+If you set "fsp,enable-memory-down" you are strongly encouraged to provide an
+"fsp,memory-down-params{};" to specify how your memory is configured.  If you do
+not set "fsp,enable-memory-down", then the DIMM SPD information will be
+discovered by the FSP and used to setup main memory.
