This change adds logic to determine dsc switch based on
the connector property "CONNECTOR_PROP_DSC_MODE" and
performs seamless DSC switch if there is any change in
DSC configuration. The connector property is populated
in msm_sub_mode based on which suitable mode is selected.

Commit a25b988ff83f ("drm/bridge: Extend bridge API to
disable connector creation") and commit ee68c743f8d0 ("drm: Stop
including drm_bridge.h from drm_crtc.h) add additional input flags.
This change adds fixes to the drm bridge attach API and includes
relevant drm_bridge header files.

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.

Primary and secondary dsi displays are built-in displays
and they are supported during all concurrency usecases
without resource allocation failure. DP mode filter
logic should provide supported mode information based
on free mdp resources after dsi resource assignment.

Add the colorspace property for DP controller for MSM. Also, change
the default method to send the colorimetry information to the sink
from MISC bits of MSA to VSC SDP packets if the sink supports it. This
helps to avoid dynamic switches between the packet types for sending
the colorimetry information during BT2020 and DCI-P3 use-cases.
