[U-Boot] [U-Boot, 05/15] spl: fit: implement fdt_record_loadable

[Philipp Tomsich]

> During the loading of more complex FIT images (e.g. when the invoked
> next stage needs to find additional firmware for a power-management
> core... or if there are multiple images for different privilege levels
> started in parallel), it is helpful to create a record of what images
> are loaded where: if a FDT is loaded for one of the next stages, it
> can be used to convey the status and location of loadables.
> 
> This adds a fdt_record_loadable() function that can be invoked to
> record the status of each loadable below the /fit-images path.
