Two weeks ago, we sent the patch to set disable_power_well=0, this is
because we found sometimes the hdmi audio driver printed out the timeout
errors when accessing the codec. But recently the ODM told us those
machines had some HW or BIOS issues, we can't reproduce the timeout
errors on the new machines anymore even without this patch. And moreover
we need put the CPU into PC10 power state to meet the E-star starndard,
we need to revert this patch.

Revert the patch.

[Test Case]
Tested on the new icl laptops, we have not reproduce the timeout errors,
and The PC can enter PC10.

[Regression Risk]
Low. We have done many tests.
