During an ESD trigger, a check must be done to ensure
that ESD is enabled on the particular panel. If not the
panel might end up in a bad state, if the trigger is
propagated successfully instead of reporting a failure.

Helper function is returning the width of single mixer. During
atomic crtc check, the number of destination scaler is not
considered before width check and can fail possible higher
resolutions. The mixerwidth should be taken as a multiple of
num_ds_enabled.

Update the minimum encryption level only when there is a request
to do so coming from the DRM framework. This will ensure that any
previously set value will not be overwritten while processing
other commands. Failure to preserve the minimum encryption level
can result in secure content playback failure if the sink device
is not updated with the correct value.

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.

Change batches max packet size and read command together, so that
for each esd read, there will not be two independent command transfers.
Without batching sometimes esd thread can hold the panel mutex for
longer time, which can cause framedrops as crtc thread can be blocked on
panel lock to send partial update command and kickoff next frame.
