Integration specific tweaks for xtensa architecture should
use Kconfig options selected for required platforms, not the
platform headers.

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.

If all symbols in menu are not selectable if some
other symbol is not present, then there is no point
in showing that menu.

Apollolake+/i.MX have reset vector in ROM. So far we have
used platform config symbols to tell which platforms have
the reset vector in ROM.
Anyhow, things are starting to get ugly here with more
platforms to come so we add an internal config symbol
which will be set by each each platform when needed.

We already have CONFIG_DEBUG* symbols in Kconfig,
this one is still defined in code, so it should be
moved also to Kconfig.

It's better to have general options earlier in menuconfig
and specific options later.

I've added counters for processed and received ipc tasks.
They are dropped after trace points in memory window.

Makes DMA FIFO partitioning configurable from Kconfig.
Some platforms need to set FIFO partitions before
enabling DMA controller.

Makes DW-DMA stop method to be configurable from Kconfig.
Some of the platforms cannot stop DMA channel immediately,
but first need to suspend and drain FIFO.

Moves configuration of aggregated channel interrupts to
Kconfig. Currently only Apollolake has possibility
to register interrupt per channel.

On i.MX we have only two software interrupts available. One is used
as PLATFORM_SCHEDULER_IRQ and the other one for PLATFORM_IRQ_TASK_HIGH.
