sparc64: use memory_region_allocate_system_memory() only for '-m' specified RAM 

memory_region_allocate_system_memory() was designed to be called for
allocating inital RAM. Using it mutiple times within one board is not
supported and could fail if -mem-path with non hugepage path is used.

Keep using memory_region_allocate_system_memory() only for initial
RAM and use memory_region_init_ram() for the rest fixed size regions.
