iwlwifi: dbg_ini: dump headers cleanup
Browse files Browse the repository at this point in the history 
Unite dump memory ranges under a single struct and add a specific header
for each type of memory.
Also, maintain a single version to all dump structures.

This cleanup is also needed for the future addition of FW notification
regions and others.
