It is to fix: MST display failed to resume from S3
At the beginning of resume from S3, need to check if mgr->aux is
NULL. Fake MST encoder doesn't have real aux channel.

Clean fake sink flag on resume if real sink connected.
Fixing S3 topology change problem like this:
1) x desktop with 1 or > displays
2) unplug display
3) suspend
4) replug same display
5) resume
without this change replugged display doesn't light up

Need to properly setup MST encoder cbs. Otherwise drm_device
encoder doesn't register its own cbs, leading to NULL
encoder->funcs in drm_atomic_helper_resume().

This is a followup to the following revert:
Rex Zhu Revert "drm/amd/display: Match actual state during S3
resume."
Three things needed to be addressed:
1. Potential memory leak on dc_state creation in atomic_check during
s3 resume
2. Warnings are now seen in dmesg during S3 resume
3. Since dc_state is now created in atomic_check, what the reverted
patch was addressing needs to be reevaluated.
This change addresses the above:
1. Since the suspend procedure calls drm_atomic_state_clear, our hook
for releasing the dc_state is called. This frees it before
atomic_check creates it during resume. The leak does not occur.
2. The dc_crtc/plane_state references kept by the atomic states need to
be released before calling atomic_check, which warns if they are
non-null. This is because atomic_check is responsible for creating
the dc_*_states. This is a special case for S3 resume, since the
atomic state duplication that occurs during suspend also copies a
reference to the dc_*_states.
3. See 2. comments are also updated to reflect this.

The atomic_check hook is expected to fail in some cases, e.g. if the
modeset operation requested by userspace cannot be performed, so it must
not spam dmesg on failure.

We need to avoid calling reset after detection because the next
commit adds freesync properties on the atomic_state which are set
during detection. Calling reset after this clears them.
The easiest way to accomplish this right now is to call ->reset on
the connector right after creation but before detection. To stay
consistent call ->reset on every other object as well after creation.
v2: Provide better reason for this change in commit msg.

For SoC's having software designed cursor plane,
should be treated differently than hardware cursor planes.
The DRM core initializes cursor plane by default with
legacy_cursor_update set.
Hence legacy_cursor_update can be use effectively
to handle software cursor planes' update and atomicity
functionalities.
This patch uses this variable to decide in the atomic_check
to whether add a requested plane to the list of affected planes or
not, hence fixing the issue of co-existence of MPO, i.e,
setting of available hardware planes like underlay and
updation of cursor planes as well.
Without this patch when underlay is set from user space,
only blank screen with backlight is visible.
