This is a partial revert of I67ace5c064b2b56d03732a78f334ea6b1b649608 which tries
to enable Sink CRC irrespective of the sink's CRC capability to workaround an
issue with a specific sinks which reports incorrect capability on first plugin.
But this causes some MST dongles to misbehave causing one or both outputs to
be blank.

Attach the dmabuf with cp-pixel vmid to secure-cb device and the
tvm vmid in HLOS to DRM device to support CSF 2.5. Some cases like
DEMURA has dmabuf set with both cp-pixel & tvm VMIDs as its used
in HLOS and shared with Trusted-vm. Attach to secure-cb device in
these cases.

For a proxy-scheduled VCPU like the TUI VM, assignment to a
physical core is a runtime decision made by the HLOS scheduler,
and it may change frequently. pm_qos vote added by PVM for
specific CPUs won't be sufficient for addressing irq latency.
This change updates votes for all possible CPUs during TVM
entry and also removes the vote during exit.

After introducing avr step state, the driver checks for avr
state none before returning early. In the case where avr property
is not being set, this leads to skipping qsync programming.
This change removes this state check.

Both trusted-vm and secure-camera preview buffers uses the same
VMID_TVM. In primary-vm, the check is used to determine the camera
preview usecase and attach it to the correct device. This is not
necessary for trusted-vm as it can default to nested trusted-vm
context bank. Avoid the check while its in trusted-vm.

Currently the ipc context for drm_dp_aux is being created

PPB size programming checks for the max horizontal width of the

it is possible that this information is not ready at this point.
However, this is not an error, as by default driver will set the
maximum size.
This change reduces the error log to a debug warning.

While same spinlock can be used to protect a critical section
in both irq-handler and in non-irq context, in non-irq context
it is mandatory to use irqsave version of locking api to disable
irqs locally on the particular cpu. Otherwise, this could lead
to a deadlock if a non-irq thread holding the spinlock and irq
handler is scheduled on same cpu.
This change replaces physical encoder spinlock locking with
irqsave version of locking api in the non-irq context.

Currently, hdcp wait loops uses the wait_event() macro which sets the
status of the thread to WAIT_UNINTERRUPTIBLE and contributes to system
load. The macro wait_event_idle() polls for a changing condition in the
same way but instead sets the thread status to WAIT_IDLE which does not
contribute to system load. This prevents hdcp threads from appearing as
hung threads in system load summaries while still properly polling for
status changes.
