Send the hotplug notification to the user space only when there
is a state change e.g. from connect to disconnect, or vice versa.
This ensures that there are no spurious notifications that are
sent to the user space.

Add the colorspace property for DP controller for MSM. Also, change
the default method to send the colorimetry information to the sink
from MISC bits of MSA to VSC SDP packets if the sink supports it. This
helps to avoid dynamic switches between the packet types for sending
the colorimetry information during BT2020 and DCI-P3 use-cases.

Populate the supported colorspaces property for DP
as part of getting the display modes.
This will expose the supported colorspaces of the sink to
userspace and in-turn the userspace shall pick the colorspace
suitable for the use-case.

Break the host initialization and de-initialization to
create late initialization and early de-initialization.
Call host init/deinit on physical connect/disconnect only
As attention messages from sink doesn't change the physical
cable configurations, call only late init/early deinit in
this case to avoid unnecessary hardware resources
re-initialization.

Update the connected state to false during display clean up. This
will allow subsequent connections to be processed correctly in

Disable audio for every active panel during display clean
up use cases when the driver times out waiting for the
video path to tear down. This ensures that the audio
subsystem is notified before the clean up shuts down the
timing engine, and also ensures that the audio module
state is correctly updated to indicate that the session
has ended. This change will reduce the likelihood of the
audio subsystem attempting to program DP audio, and also
ensure that the state checks will correctly prevent any
attempts to program audio after the session has ended.

The DP HDCP layer fails to wait on and clear its internal thread
upon an HDCP stop or failure. This can result in use after free
failures if a read or write over aux channel operation is already
queued.
Update the DP HDCP layer to stop and wait on kthread completion
upon HDCP failures, and clear the kthread command queue before
resuming kthread execution. Additionally, ensure the SDE HDCP
worker thread correctly starts and stops execution upon HDCP
enablement and disablement respectively.

In scenarios where two streams become active in a short time period, HDCP
authentication may incorrectly be kicked off twice. This occurs due to the
HDCP state machine not indicating when authentication is already in
progress.
Update the dp_dispay HDCP state machine to only transfer to the
authenticating state once authentication has begun.

If a DP stream is disconnected when HDCP is not fully authenticated,
authentication may not continue for remaining streams. This occurs
due to the worker thread rescheduling itself on auth fail while
disconnect cancels any pending work.
Update disconnect logic to wait for HDCP authentication to complete
before stream de-registration, and reschedule the HDCP worker if HDCP
did not fully authenticate prior to disconnect.
