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

This is done with the intention of supporting Universal Payload.

Currently, we read an "entry-start" prop. This should be called "entry",
awaiting the spec change here
https://github.com/UniversalPayload/spec/pull/19.

We also implement support for the "load" prop. Note that this is
implemented here as a fdt64_t, which may need to be checked against
other implementations.

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.
