Commit f15a3ea8 ("MAINTAINERS: Add ASPEED BMC GFX DRM driver entry")
does not mention that linux-aspeed@lists.ozlabs.org is moderated for
non-subscribers, but the other three entries for
linux-aspeed@lists.ozlabs.org do.

By 'majority vote' among entries, let us assume it was just missed here and
adjust it to be consistent with others.
