MSI interrupt doesn't work anymore if the HDA device ever gets runtime-suspended. [Fix] Disable runtime suspend on HDA device. This is a temporary workaround, we are still finding the root cause. [Test] 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.
