  -----------
  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.

  ppc: rs6000_mc: drop usage of memory_region_allocate_system_memory()

rs6000mc_realize() violates memory_region_allocate_system_memory() contract
by calling it multiple times which could break -mem-path. Replace it with
plain memory_region_init_ram() instead.

  hppa: drop usage of memory_region_allocate_system_memory() for ROM

machine_hppa_init() violates memory_region_allocate_system_memory() contract
by calling it multiple times which could break with -mem-path. Replace
the second usage (for 'rom') with memory_region_init_ram() instead.
