so they should be named after hashing algorithms.

Registers low latency scheduler with DMA multi channel
domain as scheduling source. This way we can finally get rid
of scheduling code from DW-DMA driver and DAI component.
Functionally it works the same as the previous implementation,
but transfers scheduling layer to the right places.

Adds PLATFORM_DW_DMA_INDEX definition. This allows
to access this value from the generic API.

Renames DMA_AGGREGATED_IRQ to DW_DMA_AGGREGATED_IRQ
definition. This is more appropriate as it's not generic
DMA setting.

Implements DMA scheduling domain. It allows to initialize
another low latency scheduler and schedule on any DMA channel.
The functionality stays the same as the one already done in
DMA drivers e.g. DW-DMA.

This way generic API can retrieve this information.

Moves CAVS_PLATFORM_NUM_DMACS definition to specific platforms

DMA channel is the source of pipeline scheduling.

Adds preload_task to pipeline. This task is only
allocated and initialized, when pipeline needs to be
preloaded with data e.g. render pipe scheduled on DMA irq.
It's always an EDF task, so we make sure it's get scheduled
no matter if interrupt was triggered or not.

Changes implementation of pipe_task allocation and initialization
to happen in prepare call instead of during pipeline creations.
It might be that the pipeline will never be used.

Changes copy method for host working in one shot mode.
Blocking copy replaces interrupt based copy. In an effort
of extracting DMA interrupt based scheduling from DMA
to scheduler we need to minimize number of irq sources
in our flows. This patch also changes the interrupt
based implementation of traces copying through DMA.

Fixes stack dump procedure for exceptions happening in interrupt
handlers. Stack base and size haven't been set to the interrupt's
one in current task context, so when exception happened during
interrupt processing we've got SOF_IPC_PANIC_STACK cause instead
of the real one.

Removes host_pending from ipc structure, because it's no
longer needed. Scheduler will automatically throw an error,
when we'll try to run not completed task.

Changes ipc task implementation, so it accepts new messages from
host in a complete task callback. This way we will avoid the
situation, where host will send another message before we
truly complete current ipc task.

Change the waiti implementation to panic only if we're
lowering current interrupt level. In some rare cases
(like entering D3 for some platforms) we don't care,
because DSP will be disabled anyway.

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.

Fix the core-isa headers for HSW and BDW.
Provide a virtual threadptr register in the memory map using a linker
