Tom Rini 6e7df1d151 global: Finish CONFIG -> CFG migration 
At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...
