lib/{fit,fit_payload}.c: Enhance support for FIT images

Implement support for loading images from FIT "firmware" props.
These do not require quirks, so the implementation is common across
architectures. This is done with the intention of supporting Universal Payload.

We implement support for the "load" and "entry" props. Here, these
are implemented as fdt64_t. A follow-up will read prop-sized ints.

The selected configuration no longer requires an FDT. In this case,
we'll attempt a config matching the board ID, then fallback to the
FIT default compat.
