khungtask by default monitors all tasks for long unterruptible sleep.
This change introduces a sysctl option, /proc/sys/kernel/
hung_task_selective_monitoring, to enable monitoring selected tasks.
If this sysctl option is enabled then only the tasks with
/proc/$PID/hang_detection_enabled set are to be monitored,
otherwise all tasks are monitored as default case.
Some tasks may intentionally moves to uninterruptable sleep state,
which shouldn't leads to khungtask panics, as those are recoverable
hungs. So to avoid false hung reports, add an option to select tasks
to be monitored and report/panic them only.
By default, enable the feature always to monitor selected tasks.

wait_for_completion_interruptible() returns ERESTARTSYS when
the device goes to low power mode.
The SPU subsystem is shutdown on deep low power mode,
so the interrupted operation is not recoverable.
return EINTR to user space to propagate the error to the user app.

The sample_ms should never be larger than the devfreq polling
interval. If userspace tries to configure this invalid
configuration, return an error.
Devfreq polling interval should be always greater then the
sample_ms add check in the governor interval event to update
the polling interval accordingly.
