Change the 'ret' variable from u32 to int to store -EINVAL. Storing the
negative error codes in unsigned type, doesn't cause an issue at runtime
but it's ugly as pants.
Additionally, assigning -EINVAL to u32 ret (i.e., u32 ret = -EINVAL) may
trigger a GCC warning when the -Wsign-conversion flag is enabled.

Among the scheduler's statuses, the only one that indicates an error is
DRM_GPU_SCHED_STAT_ENODEV. Any status other than DRM_GPU_SCHED_STAT_ENODEV
signifies that the operation succeeded and the GPU is in a nominal state.
However, to provide more information about the GPU's status, it is needed
to convey more information than just "OK".
Therefore, rename DRM_GPU_SCHED_STAT_NOMINAL to
DRM_GPU_SCHED_STAT_RESET, which better communicates the meaning of this
status. The status DRM_GPU_SCHED_STAT_RESET indicates that the GPU has
hung, but it has been successfully reset and is now in a nominal state
again.

This will be used in a later commit to trace the drm client_id in
some of the gpu_scheduler trace events.
This requires changing all the users of drm_sched_job_init to
add an extra parameter.
The newly added drm_client_id field in the drm_sched_fence is a bit
of a duplicate of the owner one. One suggestion I received was to
merge those 2 fields - this can't be done right now as amdgpu uses
some special values (AMDGPU_FENCE_OWNER_*) that can't really be
translated into a client id. Christian is working on getting rid of
those; when it's done we should be able to squash owner/drm_client_id
together.

There is a timeout failure been found during stress tests. If the firmware
generates a mailbox response right after driver clears the mailbox channel
interrupt register, the hardware will not generate an interrupt for the
response. This causes the unexpected mailbox command timeout.
To handle this failure, driver checks the interrupt register before
exiting mailbox_rx_worker(). If there is a new response, driver goes back
to process it.

It is required by firmware to wait up to 2 seconds for pending commands
before sending the destroy hardware context command. After 2 seconds
wait, if there are still pending commands, driver needs to cancel them.
So the context destroy steps need to be:
1. Stop drm scheduler. (drm_sched_entity_destroy)
2. Wait up to 2 seconds for pending commands.
3. Destroy hardware context and cancel the rest pending requests.
4. Wait all jobs associated with the hwctx are freed.
5. Free job resources.

Add SET_STATE ioctl to configure device power mode for aie2 device.
Three modes are supported initially.
POWER_MODE_DEFAULT: Enable clock gating and set DPM (Dynamic Power
Management) level to value which has been set by resource solver or
maximum DPM level the device supports.
POWER_MODE_HIGH: Enable clock gating and set DPM level to maximum DPM
level the device supports.
POWER_MODE_TURBO: Disable clock gating and set DPM level to maximum DPM
level the device supports.
Disabling clock gating means all clocks always run on full speed. And
the different clock frequency are used based on DPM level been set.
Initially, the driver set the power mode to default mode.
