v2: fix missing argument to printf() call.
v3: explain the magic "+ 7" offset into the version string
v3: avoid offset into U_BOOT_VERSION string completely and define
a new PLAIN_VERSION variable instead; this has the benefit that it
can be used in other places as well where such version information
might be needed (fw_{set,print}env etc. comes to mind).
