During DP disable, it is possible for audio and display to race
causing the audio to send teardown notification after display driver
has disabled all the clocks. This change adds a check for panel state to
avoid accessing registers during this callback.

With real DP over Type-C sinks, DP driver requests access to USB
combo PHY from USB driver. But in DP SIM mode, there is no real
sink and PD management, so the combo PHY is managed by USB driver
and DP driver uses it without actually claiming it. If the USB
cable is unplugged in this scenario, USB driver notifies the
disconnection through an atomic notifier call. It does not expect
the handler to go into sleep, but the disconnect handler inside
DP driver has multiple wait for events and also sleeps to wait for
HW state updates.
This change passes a skip_wait flag to all the disable functions
to complete disconnect processing by skipping all processor sleeps
and event waits.

Verify if DP stream is still active before accessing dp audio
registers. This would prevent a scenario where audio teardown
flow is trying to access dp audio config registers after dp
has completed the deinit process.

We add support for Trusted UI (TUI) transitions and address the
following use cases:
1. Display was active before TUI start
- Power off on TUI start, power off on TUI stop
- Register access not allowed after TUI start (skip all
events except disconnect)
2. Hotplug while TUI is active
- Connect: skip sending connect uevent
- Disconnect: send disconnect uevent and skip any controller
programming
3. TUI start while processing HPD High
- Complete all connect work (and therefore any register access)
then send connect uevent
4. Audio
- Disable audio at TUI start and skip audio programming if TUI
is active

The DP display driver issues an audio disconnect notification
after the video disconnect notification. Sometimes audio driver
is waiting for the video commit to complete before turning off
the audio engine. In such cases, there is a brief screen freeze
observed on the primary. In other cases, when the off call from
audio driver gets delayed, a momentary screen freeze is seen.
The audio notification happens as part of the display commit call.
The order of notification is video and then audio while
processing display connect and the same order is followed for
disconnect also, which is causing this issue. These changes will
modify the order of notification to send audio disconnect first
and then video while processing DP cable disconnect.

Skip the wait in the disable path if the audio engine has already
been disabled or was not previously enabled. This avoids an
unnecessary wait since the audio subsystem will only acknowledge
the notification and not request a tear down if no audio playback
was started by the user.

Add a check to ensure that audio registers are programmed only
when the DP timing engine (audio session) is enabled. This will
reduce the likelihood of un-clocked register access for audio
related operations.
