All sde crtc's are virtual when they are created. Resources for the crtc
is allocated when crtc is enabled. All crtc's will not have same
capabilities because some of the dspp blocks have additional hardware
blocks. Change exposes additional dspp capabilities dynamically when
crtc is allocated the dspp hardware block.

Allow for overriding color processing features that normally uses
DSPP flush to use LM flush instead. This is required on targets
where some of the DSPP features have been tied to LM flush bits.
This changes adds a field in color processing node to track if the
override is needed and enables LM flush override for rounded corner
on target requiring it.

Fix the check for uneven split across LMs when destination
scaler is used and reject the use-case since this is not
supported by the driver. This can happen if an odd-value
for the horizontal width is being split across 2 mixers.
The existing check was broken since it uses pass-by-value
with a zero initialized value that callee tries to update
while iterating over the DS configurations. Use pass-by-
reference with the previous DS configuration, if available,
instead of just 0 values so the proper comparisons can take
place.

A new status register was added in DPU 5.x to INTFs to allow for
confirmation when the timing engine is disabled. This
functionality was controlled via an overloaded feature flag
which is used to enable INTF tear-check ops (also added in DPU
5.x). External displays support INTF_STATUS but have no use for
any tear-check functions. Separate these features so they can be
enabled individually on the interfaces which support them.

A mode switch on a real monitor can be triggered by forcing the new
mode using debugfs and initiating an hpd_irq. Due to a missing
check for simulator state, the current driver calls the hpd_irq
callback for simulator even for a real monitor. This change adds
this check.

DP MST driver registers bridge callback functions with the DRM framework.
mst_lock is used for synchronization of the mst bridge functions. These
functions call into dp_display where a session lock is obtained for
the display. HPD callbacks, on the other hand, are first handled by
dp_display. During these callbacks, dp_display takes a session lock
first before calling into DP MST driver layer. Currently, the DP MST
layer waits on mst_lock which can result in a deadlock.
This change removes the usage of mst_lock inside hpd callback functions
and just uses the session lock for synchronization.

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 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.
