Bug Description

Headset jack detection doesn't work on Dell UFF desktops. MSI interrupt
doesn't work anymore if the HDA device ever gets runtime-suspended.

Disable runtime suspend on HDA device.
This is a temporary workaround, we are still finding the root cause.

With the patch applied, jack detection always works.

[Regression Potential]
This fix will not enable HDA runtime suspend by defualt, so for systems
that doesn't use TLP or `powertop --auto-tune`, this will slightly
increase power consumption.
