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.

Since commit 4a97a3da42 ("drm: Don't update property values for atomic
drivers") atomic drivers must not update property values as properties
are read from the state instead. To catch remaining users, the
drm_object_property_set_value() function now throws a warning when
called by atomic drivers on non-immutable properties, and we hit that
warning when creating connectors.
The easy fix is to just remove the drm_object_property_set_value() as it
is used here to set the initial value of the connector's DPMS property
to OFF. The DPMS property applies on top of the connector's state crtc
pointer (initialized to NULL) that is the main connector on/off control,
and should thus default to ON.

Currently the mailbox framework sets txdone_method to TXDONE_BY_POLL if
the controller sets txdone_by_poll. However some clients can have a
mechanism to do TXDONE_BY_ACK which they can specify by knows_txdone.
However, we endup setting both TXDONE_BY_POLL and TXDONE_BY_ACK in that
case. In such scenario, we may end up with below warnings as the tx
ticker is run both by mailbox framework and the client.

The spec file always passes %{?_smp_mflags}, but we have two
problems here.
[1] "make -jN rpm-pkg" emits the following warning message:
make[2]: warning: -jN forced in submake: disabling jobserver mode.
[2] We can not specify the number of jobs that run in parallel.
Whether we give -jN or not from the top Makefile, the spec file
always passes ${?_smp_mflags} to the build commands.
${?_smp_mflags} will be useful when we run rpmbuild by hand. When we
invoke it from Makefile, -jN is propagated down to submake; it should
not be overridden because we want to respect the number of jobs given
by the user. Set _smp_mflags to empty string in this case.
