During resume, the steer semaphore on GT1 was observed to be held. The
hardware team has confirmed the safety of clearing steer semaphores
for all GTs during driver load/resume, as no lock acquisitions can occur
in this process by other agents.
v2: reset on resume not in intel_gt_init().
v3: do the reset on intel_gt_resume_early()
v4: do general sanitization for all GTs(Matt)

drm-misc-next for v6.7-rc1:
UAPI Changes:
- drm_file owner is now updated during use, in the case of a drm fd
opened by the display server for a client, the correct owner is
displayed.
- Qaic gains support for the QAIC_DETACH_SLICE_BO ioctl to allow bo
recycling.
Cross-subsystem Changes:
- Disable boot logo for au1200fb, mmpfb and unexport logo helpers.
Only fbcon should manage display of logo.
- Update freescale in MAINTAINERS.
- Add some bridge files to bridge in MAINTAINERS.
- Update gma500 driver repo in MAINTAINERS to point to drm-misc.
Core Changes:
- Move size computations to drm buddy allocator.
- Make drm_atomic_helper_shutdown(NULL) a nop.
- Assorted small fixes in drm_debugfs, DP-MST payload addition error handling.
- Fix DRM_BRIDGE_ATTACH_NO_CONNECTOR handling.
- Handle bad (h/v)sync_end in EDID by clipping to htotal.
- Build GPUVM as a module.
Driver Changes:
- Simple drivers don't need to cache prepared result.
- Call drm_atomic_helper_shutdown() in shutdown/unbind for a whole lot
more drm drivers.
- Assorted small fixes in amdgpu, ssd130x, bridge/it6621, accel/qaic,
nouveau, tc358768.
- Add NV12 for komeda writeback.
- Add arbitration lost event to synopsis/dw-hdmi-cec.
- Speed up s/r in nouveau by not restoring some big bo's.
- Assorted nouveau display rework in preparation for GSP-RM,
especially related to how the modeset sequence works and
the DP sequence in relation to link training.
- Update anx7816 panel.
- Support NVSYNC and NHSYNC in tegra.
- Allow multiple power domains in simple driver.

[WHY]
Writeback connectors are based on a different object:
drm_writeback_connector, and are therefore different from
amdgpu_dm_connector. We need to be careful to ensure code
designed for amdgpu_dm_connector doesn't inadvertently try
to operate on a drm_writeback_connector.
[HOW]
Skip them when connector type is DRM_MODE_CONNECTOR_WRITEBACK.

As part of IP discovery early_init is run for all HW IP blocks.
During this phase all firmware is supposed to be identified that may
be missing so that the driver can avoid releasing resources used by
the EFI framebuffer or simpledrm until the last possible moment.

This patch fixes a null pointer dereference in the error message that is
printed when the Display Core (DC) fails to initialize. The original
message includes the DC version number, which is undefined if the DC is
not initialized.

The error path for SDMA firmware loading is unnecessarily noisy.
When a firmware is missing 3 errors show up:
```
amdgpu 0000:07:00.0: Direct firmware load for amdgpu/green_sardine_sdma.bin failed with error -2
[drm:sdma_v4_0_early_init [amdgpu]] *ERROR* Failed to load sdma firmware!
[drm:amdgpu_device_init [amdgpu]] *ERROR* early_init of IP block <sdma_v4_0> failed -19
```
The error code for the device init is bubbled up already, remove the
second one.

[Why & How]
These DPCD addresses are either declared in other header files
where it makes more sense or simply not used by any DC code.
