{cpu,soc}/intel: remove unused smm_init() function
There used to be a need for an empty smm_init() function because initialize_cpus() called it even though nothing called initialize_cpus(). However, garbage collection at link time is implemented so there's no reason to provide an empty function to satisfy a symbol that is completely culled during link. Remove it.
