We only use S1Translate::out_secure in two places, where we are
setting up MemTxAttrs for a page table load. We can use
arm_space_is_secure(ptw->out_space) instead, which guarantees
that we're setting the MemTxAttrs secure and space fields
consistently, and allows us to drop the out_secure field in
S1Translate entirely.
