spl: fit: Allow the board to tell if more images must be loaded from FIT
spl_fit_get_image_name() is used to get the names of the images that the
SPL must load from the FIT. It relies on the content of a property present
in the FIT. The list of images is thus statically defined in the FIT.
With this scheme, it quickly becomes hard to manage combinations of more
than a handful of images.
To address this problem, give the board driver code the opportunity to
add to the list of images. The images from the FIT property are loaded
first, and then the board_get_fit_loadable() is called to get more image
names.

ARM: mxs: spl_boot.c: make early_delay more robust
It's true that booting normally doesn't take long enough for the
register to roll (which actually happens in a little over an hour, not
just a few seconds). However, the counter starts at power-on, and if
the board is held in reset to be booted over USB, one actually risks
hitting wrap-around during boot, which can both result in too short
delays (if the "st += delay" calculation makes st small) and
theoretically also unbound delays (if st ends up being UINT_MAX and
one just misses sampling digctl_microseconds at that point).
It doesn't take more code to DTRT, and once bitten, twice shy.

This has the advantage that the user does not need to know to which

Cortex-M4 core memory addresses to primary/host CPU memory
addresses (Cortex A7/A9 cores).
This allows to boot firmwares from any location with just using
