This keeps both sides somewhat in sync and should make Dave Gordon happy. Note that both the wa and the golden context init code suffer a bit from an inssuficient split into driver load and hw init code. Which means we have a bunch of tests all over the place to check whether the one-time initialization has been done already or not. All that one-tim code should be moved into the one-time ring setup code, but that's work for later.
