commit 5bbccadaf33eea2b879d8326ad59ae0663be47d1 upstream.
With hardware scheduler it is not expected to receive JOB_DONE
notifications from NPU FW for the jobs aborted due to command queue destroy
JSM command.
Remove jobs submitted to unregistered command queue from submitted_jobs_xa
to avoid triggering a TDR in such case.
Add explicit submitted_jobs_lock that protects access to list of submitted
jobs which is now used to find jobs to abort.
Move context abort procedure to separate work queue not to slow down
handling of IPCs or DCT requests in case where job abort takes longer,
especially when destruction of the last job of a specific context results
in context release.

[ Upstream commit 436b67d6936b5658426e40d0df8f147239bc532b ]
Add ivpu_fw_sched_mode_select() function that can select scheduling mode
based on HW and FW versions. This prepares for a switch to HWS on
selected platforms.

The driver tracks the time spent by NPU executing jobs
and shares it through sysfs `npu_busy_time_us` file.
It can be then used by user space applications to monitor device
utilization.
NPU is considered 'busy' starting with a first job submitted
to firmware and ending when there is no more jobs pending/executing.
