[PATCH 0/7] SPL: FIT: Bring the SPL_LOAD_FIT path in line with documentation

When I wrote commit 4afc4f37c70e ("doc: FIT image: Clarify format and
simplify syntax"), I did not expect it to go through without
objection. I didn't also write the code to go along with it. This
series fixes that by updating one of the three FIT code paths to be
compliant.

There are three code paths that deal with loading a FIT:
  * 'bootm' command
  * SPL_LOAD_FIT
  * SPL_LOAD_FIT_FULL
  
I chose to start with SPL_LOAD_FIT, because that's the code I'm most
familiar with. Also, by its simplicity, it is the most generic FIT
loading code, and the easiest to make compliant.

I also chose not to fix every nook and cranny because nobody is using
those corner cases -- as evidenced by the lack of support. Instead, I
chose to document known limitations.

  spl: fit: Don't overwrite previous loadable if "load" is missing
  doc: FIT image: Introduce "u-boot,fpga-legacy" property
  spl: fit: Move FPGA loading code to separate functions
  spl: fit: Warn if FIT contains "fpga" property in config node
  spl: fit: Support loading FPGA images from list of "loadables"
  Kconfig: Document the limitations of the simple SPL_LOAD_FIT path
  doc: FIT image: Update FPGA example to make use of "loadables"
