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.
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.
