I think anyone is allowed as long as they do something significant (ex: Be Dragonborn, become leader of a famous guild/group, etc.), show some skill in battle, and worship the Nordic pantheon, and that is why you are presented with options based on what you've achieved when Tsun asks (if you haven't completed any guild questline, then the default is saying you're the Dragonborn). The reason there are only Nords in Sovngaarde is because Nords are the primary followers of the Nordic pantheon. The reason the Ebony Warrior isn't in Sovngaarde? DLC limitations aside, maybe he commited dishonorable acts in life that prompted him to seek an honorable warrior's death (but in the end, his previous hishonorable acts barred him entry from Sovngaarde). It's a stretch, but yeah there's my theory.
