soc/amd/cezanne/cpu: make sure that MAX_CPUS isn't overridden
Trying to limit the number of available cores by setting the MAX_CPUS Kconfig option to a lower value than the SoC's default might result in cores being enabled in the FSP-S, but not fully initialized in coreboot which will cause some malfunction. Add a static assert to make sure that this option isn't changed from the default. To limit the maximum number of cores, use the downcore_mode and disable_smt devicetree settings instead. BUG=b:184162768 TEST=Build fails if MAX_CPUS isn't the expected default.
