drm/i915: Fix VLV/CHV HDMI/DP audio enable 

Despite what I claimed in commit c3c5dc1d92
("drm/i915/audio: Do the vblank waits") the vblank
interrupts are in fact not enabled yet when we do the
audio enable sequence on VLV/CHV (all other platforms are
fine).

Reorder the enable sequence on VLV/CHV to match that of the
other platforms so that the audio enable happens after the
pipe has been enabled.

Fixes: c3c5dc1d92 ("drm/i915/audio: Do the vblank waits")
