acpi-build: remove dependency from ram_addr.h
ram_addr_t is an internal interface, everyone should go through MemoryRegion. Clean it up by making rom_add_blob return a MemoryRegion* and using the new qemu_ram_resize infrastructure. Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
