Public bug reported:
[Impact]
DP/HDMI audio on AMD PRO VII stops working after S3.
[Fix]
Ensure HDA function is suspended before ASIC reset so the subsequent
resume can be carried out successfully.
[Test]
With the patch applied, DP/HDMI audio continues to work after S3.
[Where problems could occur]
The suspend_noirq phase should not trigger any interrupt, so if
amdgpu_asic_reset() somehow raised IRQ, it can break the system.
