binman: Plumb expanded entries through fully 

Add support for this feature in the control, image and section modules, so
that expanded entries will be selected by default. So far there are no
expanded entry types, so this is a nop.

a file rather than generated. In that case we obviously don't need
the entry arguments since the contents already exists.
use_expanded: True if we are updating the FDT wth entry offsets, etc.
and should use the expanded versions of the U-Boot entries.
Any entry type that includes a devicetree must put it in a
separate entry so that it will be updated. For example. 'u-boot'
normally just picks up 'u-boot.bin' which includes the
devicetree, but this is not updateable, since it comes into
binman as one piece and binman doesn't know that it is actually
an executable followed by a devicetree. Of course it could be
taught this, but then when reading an image (e.g. 'binman ls')
it may need to be able to split the devicetree out of the image
in order to determine the location of things. Instead we choose
to ignore 'u-boot-bin' in this case, and build it ourselves in
binman with 'u-boot-dtb.bin' and 'u-boot.dtb'. See
Entry_u_boot_expanded and Entry_blob_phase for details.
