Revert "drm/i915: correctly order the ring init sequence"

This reverts 622ecb9ace2ec006b58f6779732961945ea303ca which is
commit 0d8957c8a90bbb5d34fab9a304459448a5131e06 upstream.

We may only start to set up the new register values after having
confirmed that the ring is truely off. Otherwise the hw might lose the
newly written register values. This is caught later on in the init
sequence, when we check whether the register writes have stuck.
