[PATCH 03/11] binman: Add support for a collection of entries

[Simon Glass]

The vblock entry type includes code to collect the data from a number of
other entries (not necessarily subentries) and concatenating it. This is
a useful feature for other entry types.

Make it a base class, so that vblock can use it, along with other entry
types.
