FDT support is used for both FIT style images and for architectures
that can pass a fdt blob to an OS (ppc, m68k, sparc).

For other architectures and boards which do not pass a fdt blob to an
OS but want to use the new uImage format, we just need FIT support.

Now we can have the 4 following configurations :

1) FIT only             CONFIG_FIT
2) fdt blob only        CONFIG_OF_LIBFDT
3) both                 CONFIG_OF_LIBFDT & CONFIG_FIT
4) none                 none

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Modify libfdt/Makefile to conditionally compile the *.c files based
on the board config.

This change is in preparation for condtitionial compile support in the
build system.  By spliting them all into seperate lines now, subsequent
patches that change 'COBJS-y += ' into 'COBJS-$(CONFIG_<blah>) += ' will
be less invasive and easier to review

Changes to David Gibson's original source to fit into u-boot's
environment.  No functionality changes.

This adds the applicable libfdt source files (unmodified) and a README
to explain where the source came from.
