Simon Glass 13d06981a9 image: Add device tree setup to image library 
This seems to be a common function for several architectures, so create
a common function rather than duplicating the code in each arch.

Also make an attempt to avoid introducing #ifdefs in the new code, partly
by removing useless #ifdefs around function declarations in the image.h
header.

/*
* Image Types
*
* "Standalone Programs" are directly runnable in the environment
* provided by U-Boot; it is expected that (if they behave
* well) you can continue to work in U-Boot after return from
* the Standalone Program.
* "OS Kernel Images" are usually images of some Embedded OS which
* will take over control completely. Usually these programs
* will install their own set of exception handlers, device
* drivers, set up the MMU, etc. - this means, that you cannot
* expect to re-enter U-Boot except by resetting the CPU.
* "RAMDisk Images" are more or less just data blocks, and their
* parameters (address, size) are passed to an OS kernel that is
* being started.
* "Multi-File Images" contain several images, typically an OS
* (Linux) kernel image and one or more data images like
* RAMDisks. This construct is useful for instance when you want
* to boot over the network using BOOTP etc., where the boot
* server provides just a single image file, but you want to get
* for instance an OS kernel and a RAMDisk image.
*
* "Multi-File Images" start with a list of image sizes, each
* image size (in bytes) specified by an "uint32_t" in network
* byte order. This list is terminated by an "(uint32_t)0".
* Immediately after the terminating 0 follow the images, one by
* one, all aligned on "uint32_t" boundaries (size rounded up to
* a multiple of 4 bytes - except for the last file).
*
* "Firmware Images" are binary images containing firmware (like
* U-Boot or FPGA images) which usually will be programmed to
* flash memory.
*
* "Script files" are command sequences that will be executed by
* U-Boot's command interpreter; this feature is especially
* useful when you configure U-Boot to use a real shell (hush)
* as command interpreter (=> Shell Scripts).
