Bug description:
  [Impact]
  On the machines with legacy HDA audio driver, when users plug a hdmi/dp 
monitor, the active output device is still speaker, need users to manually 
select the hdmi, then the hdmi audio will be the users' preference, once it is 
plugged, it should become the active output automatically. But with the current 
PA, after reboot and suspend/resume, the hdmi can't change to be active output 
automatically anymore.

  [Fix]
  Backport an upstream fix, this will fix the issue of "preferred ports being 
cleaned by a mistake"

  [Test]
  On a machine with legacy HDA audio driver, install the patched pulseaudio, 
then run 'rm ~/.config/pulse/*; reboot', plug a hdmi monitor, select the hdmi 
audio to be active, with the hdmi monitor plugged and reboot, suspend and 
resume, check what is the active output, it is still the hdmi audio.

  [Where problems could occur]
  This patch is in the card-restore.c, if it could introduce regression, it 
will be on the default active input/output devices, for example, users select a 
input or output device to be active, after reboot, if those devices are 
available, they should be active, but they could be replaced by other devices 
if a regression is introduced. But this possibility is very low since we tested 
the patch on a couple of desktop and laptop machines.
