[Why]
DTM topology updates happens by default now. This results in DTM
warnings when hdcp is not even being enabled. This spams the dmesg
and doesn't effect normal display functionality so it is better to log it
using DRM_DEBUG_KMS()
[How]
Change the DRM_WARN() to DRM_DEBUG_KMS()

The firmware provided via MODULE_FIRMWARE appears in the
module information. External tools(eg. dracut) may use the
list of fw files to include them as appropriate in an initramfs,
thus missing declaration will lead to request firmware failure
in boot time.

Don't check drm_crtc_state::active for this either, per its
documentation in include/drm/drm_crtc.h:
* Hence drivers must not consult @active in their various
* &drm_mode_config_funcs.atomic_check callback to reject an atomic
* commit.
atomic_remove_fb disables the CRTC as needed for disabling the primary
plane.
This prevents at least the following problems if the primary plane gets
disabled (e.g. due to destroying the FB assigned to the primary plane,
as happens e.g. with mutter in Wayland mode):
* The legacy cursor ioctl returned EINVAL for a non-0 cursor FB ID
(which enables the cursor plane).
* If the cursor plane was enabled, changing the legacy DPMS property
value from off to on returned EINVAL.
v2:
* Minor changes to code comment and commit log, per review feedback.

[Why]
Previously we were only calling add_topology when hdcp was being enabled.
Now we call add_topology by default so the ERROR messages are printed if
the firmware is not loaded.
This error message is not relevant for normal display functionality so
no need to print a ERROR message.
[How]
Change DRM_ERROR to DRM_INFO

In the resume stage of GPU recovery, start_cpsch will call pm_init
which set pm->allocated as false, cause the next pm_release_ib has
no chance to release ib memory.
Add pm_release_ib in stop_cpsch which will be called in the suspend

Due to hardware bugs, scatter/gather display on raven requires
a 1:1 IOMMU mapping, however, SME (System Memory Encryption)
requires an indirect IOMMU mapping because the encryption bit
is beyond the DMA mask of the chip. As such, the two are
incompatible.
