This change allows dynamic refresh trigger to sw trigger
and mdp intf flush. With this we can make sure that DSI
timing/clock update and mdp intf timings are updated in
one vsync.

This change resets the mixer swapping flag in crtc on a
seamless mode switch. In case of switching from command
mode to video mode it is a seamless mode on crtc, but we
disable connector and encoder. Due to this crtc fails to
reset the mixer swap since it is tied to dsc merge topology
on master connector. In transient state master connector
is not set and is set only after enabling the new mode on
connector.

The lock used by the dp debug driver to synchronize the maintenance

The simulation case uses dp_mst_sim_detect_port which
calls the drm detect port function after checking
the mst state. The non simulation case calls the drm
function directly.
This leads to cases in the disconnect path where
connectors are detected while being unregistered.
This solution merges the simulation and non simulation
cases by using the same detect port function, where a
check for mst state is performed before calling the
drm function.

When DRM property objects are created, the DRM framework attaches a
dellocator which can eventually free the object when the last reference
is removed from it. The framework can only do this before the driver is
registered. If a property is created after the registration then the
framework is unable to attach a deallocator causing a memory leak during
tear down.
The current DP driver creates a new colorspace property whenever a
new dp connector is initialized. It creates a base connector at probe
time prior to registration. But then it also creates new connectors,
post registration, whenever a new MST dongle is attached to the
topology, causing memory leaks.
This change limits the property creation to the base connector and
attaches the same object to MST connectors to avoid memory leak.

LM size does not need to be reprogrammed on every frame. Add
a check to only reprogram it when the size changes (or coming
out of power collapse). Some color processing features require
an update when this happens as well (i.e. resolution switch,
partial update, or dest scaler reconfigure). This patch allows
for notifying CP of the updated dimensions when a change occurs.

To disable the debug feature
echo 0 > /d/<panel_name>/dsi-ctrl-0/enable_cmd_dma_stats.
To read line count value:
