The debugfs api for mst control is a multi stage process where the
connector id is selected using the mst_con_id node, which is then
used on other commands such as edid_modes_mst for mode switch.
During mode switch control, the mode is set using the current id
for a display and then the switch is initiated through an unplug
and replug. But on an unplug the connector is destroyed and a new
id is assinged for that display on the subsequent plug. This
change detects this scenario and updates the cached connector id
with the id from the newly created connector.

On hpd low signaling, if MST is enabled, then the dp driver should
send the uevent to usermode and wait for the displays to be turned
off before destroying the connectors. In the current mst driver,
hpd low handling is a monolithic step. This change breaks this
into two separate callbacks into the mst driver so the display
driver can wait for usermode completion between these two steps.
When processing hpd low in sim mode, the mst driver uses the drm
framework's the port detection function. When hpd unplug is signaled
to the usermode, it checks the port status before disabling it. But
since the port hasn't been destroyed yet, the framework reports that
the port as still connected. This causes the driver to timeout while
waiting for the the displays to be disabled. This change adds a
wrapper which will report the port status as disconnected when hpd
low is signaled.

During a dynamic mode switch if the DSI clocks need to be changed,
it would result in a sequence of clock off and on operations. If
this happens after a partial update even though the commands are
sent with an asynchronous wait flag, the clock off forces the commit
thread to wait till the DSI command wait_for_done thread is
scheduled and completed. The change ensures that the clock change is
the first operation that occurs during pre kickoff.

This change add right only pu support by allowing the dsc to be
flushed when one of the dsc is getting disabled. Since the crtc
swaps the mixers in case of right only partial update, this change
fixes the active display mask passed to encoder so that always the
left only dsc gets programmed. This change also fixes layer mixer
configuration where only one layer mixer is driving the partial
update, the other mixer's configuration is disabled.

When LTM is turning off, user space will turn off LTM histogram and
then wait for LTM hist off event from driver to change the state
from offpending to off. But if device enters IPC during this time,
driver will not notify user space with LTM hist off event and LTM
will stuck in offpending state. This change remove the check
before LTM hist off event notification to avoid LTM state stuck issue.
