b8790ebeec doc: FIT image: fix incorrect examples of DT node unit address
The DT spec demands a unit-address of a node name to match the "reg"
property in that node. Newer dtc versions will throw warnings if this is
not the case.
Fix all occurences in the FIT image example files where this was not
observed, to not give bad examples to the reader.

411cf32d20 SPL: FIT: allow loading multiple images
So far we were not using the FIT image format to its full potential:
The SPL FIT loader was just loading the first image from the /images
node plus one of the listed DTBs.
Now with the refactored loader code it's easy to load an arbitrary
number of images in addition to the two mentioned above.
As described in the FIT image source file format description, iterate
over all images listed at the "loadables" property in the configuration
node and load every image at its desired location.
This allows to load any kind of images:
- firmware images to execute before U-Boot proper (for instance
  ARM Trusted Firmware (ATF))
- firmware images for management processors (SCP, arisc, ...)
- firmware images for devices like WiFi controllers
- bit files for FPGAs
- additional configuration data
- kernels and/or ramdisks
The actual usage of this feature would be platform and/or board specific.

Also update the FIT documentation to mention the new SPL feature and
provide an example .its file to demonstrate its features.
