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.
