spl: LOAD_FIT_FULL: Fix selection of the "fdt" node 

The correct FDT to use is described by the "fdt" property of the
configuration node. When the fit_unamep argument to fit_image_load()
is "fdt", we get the "/images/fdt" node. This is incorrect, as it
ignores the "fdt" property of the config node, and in most cases,
the "/images/fdt" node doesn't exist.

Use NULL for the 'fit_unamep' argument. With NULL, fit_image_load()
uses the IH_TYPE_FLATDT value to read the config property "fdt",
which points to the correct FDT node(s).

fit_image_load() should probably be split into a function that reads
an image by name, and one that reads an image by config reference. I
don't make those decisions, I just point out the craziness.
