coreboot_tables: Minor refactoring to reduce redundant data structures

Browse source 
There are three Coreboot table tags that all define some kind of memory
region, and each has their own homologous struct. I'm about to add a
fourth so I'll just clean this up and turn it into a generic struct
lb_range instead.
