[new uImage] Update naming convention for bootm/uImage related code
This patch introduces the following prefix convention for the image format handling and bootm related code: genimg_ - dual format shared code image_ - legacy uImage format specific code fit_ - new uImage format specific code boot_ - booting process related code Related routines are renamed and a few pieces of code are moved around and re-grouped.
