[Intel-gfx] [PATCH 2/2] drm/i915: hsw+ audio regs are per-transocder

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

s/pipe/transcoder/ when dealing with hsw+ audio registers. This
won't actually make any real difference since there is no audio
on the EDP transcoder. But this should avoid a bit of confusion
when cross checking against the spec.
