Both qemu_minrampagesize() and qemu_maxrampagesize() are
related to host memory backends, having the following call
stack:
qemu_minrampagesize()
-> find_min_backend_pagesize()
-> object_dynamic_cast(obj, TYPE_MEMORY_BACKEND)
qemu_maxrampagesize()
-> find_max_backend_pagesize()
-> object_dynamic_cast(obj, TYPE_MEMORY_BACKEND)
Having TYPE_MEMORY_BACKEND defined in "system/hostmem.h":
include/system/hostmem.h:23:#define TYPE_MEMORY_BACKEND "memory-backend"
Move their prototype declaration to "system/hostmem.h".
