drm/i915/audio: fix hdmi audio noise issue

Some monitors will have noise or even no sound after
applying the patch 6014ac12.

In patch 6014ac12, it will reset the cts value to 0 for HDMI.
However, we need to disable Enable CTS or M Prog bit. This is
the initial setting after HW reset.

Fixes: 6014ac122ed0 ("drm/i915/audio: set proper N/M in modeset")
