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.
