Adds complete callback to task. Some EDF tasks will need to have
additional callback on task completion, which will be executed
in critical section along the setting task state to complete.
Doing it during regular execution is not enough, because it's done
on passive level and we want to avoid any race condition.

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.

This patch implements the new version of EDF scheduler.
This is the first basic implementation, which can be easily extended
in the future.
Previous implementation had two major flaws:
- Tasks could only be preempted based on the interrupt level on which
they have been scheduled, so it was limited based on the hardware.
- This led to the system not fully utilized, so we could never achieve
full EDF functionality.
The new implementation uses only one software interrupt and allows for
dynamic context switching between different tasks based on the deadline.
Also for some cases priority is taken into consideration e.g. for idle
and almost idle tasks, which don't have deadline at all and should be
executed only if the system is free. All other normal tasks should have
the same priority. Task chosen to be run is executed on passive level,
so automatically can be preempted by every interrupt. Every task has
its own private stack on which current context is saved and restored
if needed. Note that main firmware loop is task scheduled with
idle priority, so it will be executed only after every other task
is completed.

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.

Instead of returning next period, schedule functions should return
state of the executed task. Period of the tasks is set during
initialization and doesn't change dynamically, so it doesn't make
sense to return it. With the new added SOF_TASK_STATE_RESCHEDULE
we can easily decide if the task is completed or maybe need to
be run once again.

This patch adds check for sample to not exceed S24_LE range that
could happen in int32_t type storage. The existing check for
abs(delta) > 1 does not cover such case if e.g. the reference

INT24_MAX + 1.
Similar check is added for every reference volume function that

This will optimize memory usage and introduces two significant optimizations:
> Separate the memory (heaps, stack) by cores so if we will turn off a specific core we can also turn off all memory of this core.
> Remove fixed defines and gaps, previously stack was at fixed position: end of memory and buffer heap was everything between stack and fw. Now everything will be packed at sof_fw memory segment and takes only this memory which is really needed, everything else we can turn off.
Changelog:
BSS section now includes heaps and stack
Removed many heap fixed position defines
Removed gap before fw text section
memmap init is using real linker positions for heaps
Temporary stack for boot_ldr placed in heap_hp_buffer (safe)
sof fw max_size and segment limited to memory configured by memory banks count
Using new macro to stack init per core
Stack is no longer a one big block for all cores (core_count*stack_size)
System_runtime_heap and system_heap are no longer a one big block for all cores
For suecreek memory it will also introduce similar changes previously introduced
in other platforms
(One shared memory block SOF_FW for SOF_TEXT, SOF_DATA and SOF_BSS sections
Moved fw_ready near to .rodata and .data)
Memory layout for every slave core aligned to hw memory bank:
--align to memory bank--
system_heap
system_runtime_heap
stack
--align to memory bank--
next slave core..
Similar layout applies to master core
