File 0330-device_tree.c-Don-t-use-load_image.patch of Package qemu-linux-user.19799

From: Peter Maydell <peter.maydell@linaro.org>

Subject: device_tree.c: Don't use load_image()

The load_image() function is deprecated, as it does not let the
caller specify how large the buffer to read the file into is.
Instead use load_image_size().
