This change fixes the destination scaler atomic check
to support PU with CWB disable without an additional
frame in between. It also fixes the destination height
calculation.

The DP standard leaves ambiguity to if sink synchronization
will be set before auxiliary protocols such as HDCP are to begin.
Update the dp_display HDCP worker to check sink sync only if
explicitly instructed to via the new debugfs node 'hdcp_wait_sink_sync'

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.

If stream registration is invoked while HDCP is still authenticating,
the new stream information may not get sent to the downstream repeater.
Check if stream management is already in progress during stream
registration, and queue another round of stream management if so.

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.

Add runtime_pm ops support in drm driver instead
of direct sde_power_resource_enable/disable call.
It allows drm driver to use runtime pm refcount logic
to track the resources instead of custom implementation.
The change also removes the NRT_CLIENT support from
sde_power_handle code to simplify it further.

Remove the CLK_GET_RATE_NOCACHE flag from all the DP and DSI
pll clocks. This will eliminate the need to recalculate the
clock rates from HW registers when querying the rates for the
PLL clocks. This will ensure that no unclocked register accesses
are done when these clocks are queried while the display core
is power collapsed.

In continuous splash use cases, the display is enabled in
the boot-loader. During display kernel probe, to enable clocks,
the rate is calculated by reading the hardware registers before
the corresponding software rate is set. At times when these rates
are nearly equal, the call for set rate never happens. This can
cause abnormal behavior. In this change during hand-off we don't
recalculate the clock rate to ensure the software programs the clock
registers accordingly.
