scripts/coccinelle/memory-region-init-ram.cocci: New script 

Add a coccinelle script that can be used to automatically convert
manual sequences of
 memory_region_init_ram_nomigrate()
 vmstate_register_ram{,_global}()
to use the new
 memory_region_init_ram()

// Replace by-hand memory_region_init_ram_nomigrate/vmstate_register_ram
// code sequences with use of the new memory_region_init_ram function.
// Similarly for the _rom and _rom_device functions.
// We don't try to replace sequences with a non-NULL owner, because
// there are none in the tree that can be automatically converted
// (and only a handful that can be manually converted).
