[U-Boot] [PATCH] Fix FIT and fdt blob support to have CONFIG_OF_LIBFDT and CONFIG_FIT independant

[Jean-Christophe PLAGNIOL-VILLARD]

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

For other arch and board which do not pass a fdt blob to an OS but want to use
the new uImage format, we just need FIT support (ex : ARM).

Now we can have the 3 following configurations :

1) FIT only		CONFIG_FIT
2) fdt blob only	CONFIG_OF_LIBFDT
3) both			CONFIG_OF_LIBFDT & CONFIG_FIT
