Some boards need to load an ELF file using the 'loadables' property, but
the file has segments at different memory addresses. This means that it
cannot be supplied as a flat binary.
Allow generating a separate node in the FIT for each segment in the ELF,
with a different load address for each.
Also add checks that the fit,xxx directives are valid.

The current implementation sets up the FIT entries but then deletes the
'generator' ones so they don't appear in the final image.
This is a bit clumsy. We cannot build the image more than once, since the
generator entries are lost during the first build. Binman requires that
calling BuildSectionData() multiple times returns a valid result each
time.
Keep a separate, private list which includes the generator nodes and use
that where needed, to correct this problem. Ensure that the missing list
includes removed generator entries too.

At present the fit implementation creates the output tree while
scanning the FIT description. Then it updates the tree later when the
data is known.
This works, but is a bit confusing, since it requires mixing the scanning
code with the generation code, with a fix-up step at the end.
It is actually possible to do this in two phases, one to scan everything
and the other to generate the FIT. Thus the FIT is generated in one pass,
when everything is known.
Update the code accordingly. The only functional change is that the 'data'
property for each node are now last instead of first, which is really a
more natural position. Update the affected test to deal with this.
One wrinkle is that the calculated properties (image-pos, size and offset)
are now added before the FIT is generated. so we must filter these out
when copying properties from the binman description to the FIT.
Most of the change here is splitting out some of the code from the
ReadEntries() implementation into _BuildInput(). So despite the large
diff, most of the code is the same. It is not feasible to split this patch
up, so far as I can tell.

Binman keeps track of positions of each entry in the final image, but
currently this data is wrong for things included in FIT entries,
especially since a previous patch makes FIT a subclass of Section and
inherit its implementation.
There are three ways to put data into a FIT image. It can be directly
included as a "data" property, or it can be external to the FIT image
represented by an offset-size pair of properties. This external offset
is either "data-position" from the start of the FIT or "data-offset"
from the end of the FIT, and the size is "data-size" for both. However,
binman doesn't use the "data-offset" method while building FIT entries.
According to the Section docstring, its subclasses should calculate and
set the correct offsets and sizes in SetImagePos() method. Do this for
FIT subentries for the three ways mentioned above, and add tests for the
two ways binman can pack them in.

Binman's FIT entry type can have image subentries with "hash" subnodes

class and any subclass that reuses its implementation tries to process
these unconditionally. This can lead to an error when boards specify
hash algorithms that binman doesn't support, but mkimage supports.
Let entries skip processing these "hash" subnodes based on an instance
variable, and set this instance variable for FIT subsections. Also
re-enable processing of calculated and missing properties of FIT entries
which was disabled to mitigate this issue.

Binman tries to expand some entries into parts that make it up, e.g.
'u-boot' into a 'u-boot-expanded' section that contains 'u-boot-nodtb'

on them to build a correct image, as it's possible that unexpanded child
entries have no data of their own. The FIT entry type doesn't currently
do this, which means putting a "u-boot" entry inside it doesn't work as
expected.

When we read it back, there is no need to generate nodes - they already
