NOR: User's Guide updates
Remove long-obsolete text about "erase_check" affecting "flash info" output. Move parts of that text to "protect_check", where it's still relevant; and update the "flash info" description to mention the issue. (This is still awkward. It might be best to make "protect_check" mirror "erase_check" by dumping what it finds, so "flash info" doesn't dump any potentially-stale cache info.)
