[04/12] macfb: use memory_region_init_ram() in macfb_common_realize() for the framebuffer

Currently macfb_common_realize() defines the framebuffer RAM memory region as
being non-migrateable but then immediately registers it for migration. Replace
memory_region_init_ram_nomigrate() with memory_region_init_ram() which is clearer
and does exactly the same thing.
