Create a new boot/ directory

Quite a lot of the code in common/relates to booting and images. Before adding more it seems like a good time to move the code into its own directory. Most files with 'boot' or 'image' in them are moved, except: - autoboot.c which relates to U-Boot automatically running a script - bootstage.c which relates to U-Boot timing Drop the removal of boot* files from the output directory, since this interfers with the symlinks created by tools and there does not appear to be any such file from my brief testing.
