I checked a series in last week which switches everything to
inner-shareable, it should be in the master development branch already.
See the changes up to and including:
        commit 8200daed053bc7f3dca4ee5b42d9f84934b998d7

            xen: arm: make stage 2 page tables walks inner-shareable

It's possible I missed an outer/inner configuration setting somewhere,
if you've found one please let us know.

Ian.
