UUID objects are represented by struct sof_uuid_entry instances in SOF.
Instead of casting pointers to them to integers for passing around,
carry them as pointers until they have to be cast to integers for
packing into data structures. This also fixes printing UUID, using a
"%pU" format.

All trace entries are identified by uuids only now.
Previous TRACE_CLASS_ identification removed completely.
UUIDs are passed to the tracing subsystem inside a trace
context. Each trace context defines run-time log level.
The level is initialized to LOG_LEVEL_INFO (this may be
change per instance is needed) and may be re-configured
at run-time.

Changes schedule operations to return error in case
chosen scheduler is not found or scheduler doesn't
support mandatory operation.

Removes need to pass EDF task priority during initialization.
Also removes priority definitions, which were only used by
EDF scheduler. Priorities of EDF tasks are now deprecated.
We are scheduling based only on deadline.

Extracts task operations to separate struct. This way we can
add additional ops without need to endlessly adding parameters
to schedule_edf_task_init function.

Separates task init functions for all currently supported schedulers.
Some of the parameters are not common, so there is no need to
artificially extend function signatures.

Changes scheduler_init_edf and task_main_init function
definitions as sof structure is no longer needed. It was
only used to pass agent object to main idle task.

Refactors schedule code in order to allow dynamic scheduler
creation. We don't want to add every new scheduler to the static
array of scheduler_ops and also we don't want to have every
scheduler created on every platform. Maybe some of the platforms
won't need some of the future scheduler types.

Passes sof context structure to the schedulers during
scheduler initialization. It will be required by the new
EDF scheduler.

Replaces spin_lock_* macros with irq_local_* macros
in many places. Most of the code doesn't need to keep
synchronization between cores. Setting critical section
by disabling local interrupts is enough. Spinlocks should
be used only in the places, where both cores have access.

Extracts flags to generic task data, so there is no need
for ll_schedule to keep them privately. Also changes the
way they are passed. From now on flags should be set only
during task initialization and not when starting scheduling.

Adds new period field to task private data to keep
period set during schedule. Tasks shouldn't change
their period dynamically and in fact there is no
such task.

Moves headers to dedicated directories in sof/include,
arch/include and platform/include. File tree was too flat,
so some of the files has been moved.
