<pre>At different display resolution such as 1920x1080, 1280x720, the pixel_clock is
always 25.2 MHz.
Reproduce Steps
==============
1. connect DP or HDMI cable to monitor
2. run $ intel_audio_dump | grep AUD_CONFIG, check the pixel_clock
3. change to other resolutions such as 1920x1080, 1280x720, and check the
pixel_clock
Expected Result
=============
The pixel_clock changes at different resolution. For example, 148.5 MHz at
1920x1080, 74.25 MHz at 1280x720, etc.
Actual Result
===========
The pixel_clock is always 25.2 MHz
