zephyr_dma_domain: Give semaphore resources based on sched_comp's state upon cancel
This implies the following changes:
1) domain_task_cancel() shall no longer receive the number
of tasks, but, instead, will receive the task to be cancelled.
2) zephyr_dma_domain_task_cancel() will do k_sem_give() if the
sched_comp associated with the given task is != COMP_STATE_ACTIVE.
3) SEM_LIMIT is changed to CONFIG_DMA_DOMAIN_SEM_LIMIT and can
be configured.
The reasoning for the changes are the following:
1) and 2): In the case of mixers, domain_task_cancel()'s
num_tasks is not a reliable way to determine if the DMA
IRQs got cut off. Let's consider the following scenario:
We have a mixer with 1 non-registrable pipeline task and
1 registrable pipeline task. Upon TRIGGER_STOP we'd have
the following flow (i.MX boards):
a) SAI_STOP => DMA IRQs get cut off.
b) Cancel non-registrable pipeline task.
c) Cancel registrable pipeline task.
During b) and c), domain_task_cancel() would get the following
arguments:
b) domain_task_cancel(sch, 1)
c) domain_task_cancel(sch, 1)
This is because the non-registrable pipeline task wasn't
dequeued before c) so, even though the DMA IRQs got cut
off during a), zephyr_dma_domain_task_cancel() does not give
resources to the semaphore so what happens is zephyr_ll_run()
will no longer execute and the pipeline tasks remain queued.
3) Since the semaphore can accumulate more than 1 resource
at a given time (and since it's safe to make SEM_LIMIT depend
on the load of the system), SEM_LIMIT was changed into a config.
This allows the user to change SEM_LIMIT based on the system
load. For example, if there's 2 non-registrable pipeline tasks
and 1 registrable pipeline task (same scheduling component),
an appropriate value for SEM_LIMIT should be 3 (since the
semaphore can be given at most 3 resources during the task
cancellation process). Of course, making SEM_LIMIT depend on
the system load is the worst case but this way we can make sure
that the cancelled tasks get dequeued properly.

Set this value according to the load of the system. Please make sure

that SEM_LIMIT covers the maximum number of tasks your system will be
