[SRU] [OEM-5.6] [PATCH 0/1] Fix headset jack detection on Dell UFF desktops

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1897508

[Impact]
Headset jack detection doesn't work on Dell UFF desktops. 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.
