Bug description:
[SRU Justification]
[Impact]
The system will be hold by the infinite loop in ACPI method IPCS after
exiting s2idle in TGL-H systems if the docking station with external display
connected is unplugged when the system is still in s2idle. It's
because the system is unaware of the unplug event and it seems keep something
asserted which will never be released while the system trying to exit s2idle.
[Fix]
Disconnect TypeC PHYs during system suspend and shutdown, even with the
corresponding TypeC sink still plugged to its connector. The HPD event is no
longer triggered when the system is in s2idle so the resume process will not be
hindered.
[Test Case]
1. On all TigerLake-H and later platforms with NVIDIA GPU, make sure the
NVIDIA GPU is running in either On-Demand mode or Performance mode.
2. Connect the docking station with the external display connected.
3. Suspend the system.
4. Remove the docking station when the system is suspended.
5. Press power button to wake up the system and wait > 1 minutes to make sure
if the display comes back.
[Where problems could occur]
Low. This will only make a difference in the TypeC DP alternate mode, and the
display driver will detect the display connector after resume.
========== Original Bug Description ==========
[Summary]
As mentioned in #1929166, the NVIDIA GPU will fall off the bus after exiting
s2idle in TGL-H systems if the USB Type-C docking/dongle with external display
connected is unplugged when the system is still in s2idle. The system will be
hold by the infinite loop in ACPI method IPCS and then the PCIe root port of
NVIDIA gpu fails the power transition from D3cold to D0. It's because the
display connector hotplug event not handled properly in graphics drivers and
the system will freeze for > 30 seconds to wait for ACPI method IPCS to exit.

[Reproduce Steps]
1. Connect either Dell WD19SC/DC/TB docking station(USB Type-C) to the system.
2. Connect to external display to HDMI/DisplayPort of the docking
3. Suspend the system
4. Unplug the USB Type-C connector which connects to the system
5. Press power button to wake up the system
6. Check if the internal/external display come back within 10 seconds.
[Results]
Expected:
System works with the internal/external display
Actual:
System takes > 30 seconds to get back the display.
