This currently uses _cbfs_entries[] to store entries. Since the entries
are in fact valid etypes, we may as well use the same name as
entry_Section uses, which is _entries. This allows reusing more of the

The ObtainContents() and GetEntryContents() methods in this file read
every single entry in the section. This is the common case.
However when one of the entries has had its data updated (e.g. with
'binman replace') we don't want to read it again from the file. Allow
the entry to be skipped, for this purpose. This is currently done in the
CBFS implementation, so adding it here will allow that to use more of
the entry_Section code.

For scenarios like OF_BOARD or OF_PRIOR_STAGE, no device tree blob is
provided in the U-Boot build phase hence the binman node information
is not available. In order to support such use case, a new Kconfig
option BINMAN_STANDALONE_FDT is introduced, to tell the build system
that a device tree blob containing binman node is explicitly required
when using binman to package U-Boot.

Sometimes it is useful to specify the default alignment for all entries

Generally the content of sections is not built until the final assembly
of the image. This is partly to avoid wasting time, since the entries
within sections may change multiple times as binman works through its
various stages. This works quite well since sections exist in a strict
hierarchy, so they can be processed in a depth-first manner.
However the 'collection' entry type does not have this luxury. If it
contains a section within its 'content' list, then it must produce the
section contents, if available. That section is typically a sibling
node, i.e. not part oc the collection's hierarchy.
Add a new 'required' argument to section.GetData() to support this. When
required is True, any referenced sections are immediately built. If this
is not possible (because one of the subentries does not have its data yet)
then an error is produced.
The test for this uses a 'collection' entry type, referencing a section as
its first member. This forces a call to _BuildSectionData() with required
set to False, at first, then True later, when the image is assembled.

At present, before any entry expansion is done (such as a 'files' entry
expanding out to individual entries for each file it contains), we check
the binman definition (i.e. '/binman' node) to find out what devicetree
files are used in the images.
This is a pain, since the definition may change during expansion. For
example if there is no u-boot-spl-dtb entry in the definition at the start,
we assume that the SPL devicetree is not used. But if an entry later
expands to include this, then we don't notice.
In fact the flexibility provided by the current approach of checking the
definition is not really useful. We know that we can have SPL and TPL
devicetrees. We know the pathname to each, so we can simply check if the
files are present. If they are present, we can prepare them and update
them regardless of whether they are actually used. If they are not present,
we cannot prepare/update them anyway, i.e. an error will be generated.
Simplify state.Prepare() so it uses a hard-coded list of devicetree files.
Note that state.PrepareFromLoadedData() is left untouched, since in that
case we have a complete definition from the loaded file, but cannot of
course rely on the devicetree files that created it still being present.
So in that case we still check the image defitions.
