layout: Factor out flash_region structure from romentry

The romentry structure is the container ADT with some
annotated meta-data such as 'included' or 'file' however
the substantive substructure is a 'flash_region'. Therefore
factor this out.

That is to say, the link list node 'romentry' is obscured by the implementation details of its use-case of 'flash_region' that we
clear up here.
