This turns a non-user visible symbol into a user visible one. Previously
if Xen was enabled and the other prerequisites were met you would get
dom0 support automatically -- do we really want to change that?
According to 6b0661a5e6fbf it was a deliberate decision to have it this
way.

BTW, you forgot a Signed-off-by and the appropriate CCs (please use
MAINTAINERS or ./scripts/get-maintainer.pl).
