[PATCH RESEND v2 02/32] memory: Simplify memory_region_init_rom_nomigrate() to ease review

[Philippe Mathieu-Daudé]

memory_region_init_rom_nomigrate() has the same content than
memory_region_init_ram_shared_nomigrate(), with setting the
readonly mode. The code is easier to review as creating a
readonly ram/shared/nomigrate region.
