DSI display may support video mode and command mode both and it may
support transition between these two modes.
This change adds seamless transition between these two modes for DSI
display by avoiding crtc enable/disable and panel power on/off
during modeset.

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.

On the first commit, cont splash flag is still enabled on
encoder, but connector is not yet attached. When a check-only
rm reservation is made, it does not get released due to
cont-splash check. If cont-splash is enabled, rm should
not check for connector, but directly release rsvp_nxt.

Userspace is not supposed to request vblank until crtc is enabled,
because drm framework rejects the request if crtc is not enabled.
Any vblank request prior to that need to be cached in the userspace.
Hence removing the cache logic from the downstream driver.

Current sde driver allows vblank enable and wait requests
even after crtc is disabled which would eventually lead to
enable of irq and timeouts in caller context. This change fixes
it by updating vblank callback status as 'on' during crtc enable
and shutdowns vblank callbacks before crtc disable is complete.

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.

When HDCP stream management needs to be re-performed, the SDE_HDCP state
machine breaks down and reads or writes to the wrong DPCD HDCP offsets.
This results in an authentication failure, effectively allowing stream
management to succeed only on the first attempt.
Update the SDE_HDCP stream management logic to properly take its current
state into account in re-management scenarios. This will reduce the need
for full re-authentications upon content type updates.

Commands to the HDCP protocol layer can fail or block if
executed when the system enters suspend or shutdown.
Protocol layer blockage will occur until the system returns
into a power on state, potentially resulting in deadlocks for
clients who synchronously wait on protocol layer completion.
Asynchronously handle all requests to the protocol module to
ensure that clients can make progress regardless of the state of
the underlying HDCP handler. When an already queued request is
received by the protocol module, that request will be rescheduled
to the back of the queue.
