In many places of SOF code, assumption is that code is only run
on a specific core. This allows to reduce overhead of cache
coherency management. For example this is used in the IPC stack.
In Zephyr, we can force threads to be pinned by default using
the CONFIG_SCHED_CPU_MASK_PIN_ONLY setting. Enable this setting
for all SOF builds.

Each logging backend has an overhead and we don't need two backends
writing to SRAM windows, so disable ADSP and keep MTRACE for IPC4
targets. Other targets will continue to use ADSP backend.
Due to a limitation in upstream Kconfig options, this change
will force a change in timestamp formatting as disabling ADSP
will disable CONFIG_LOG_BACKEND_FORMAT_TIMESTAMP=y. Mitigate
this by enabling CONFIG_LOG_OUTPUT_FORMAT_LINUX_TIMESTAMP=y.

The zephyr header zephyr.h should be only used with
CONFIG_LEGACY_INCLUDE_PATH, which is deprecate by both
Zephyr and SOF.
The latest zephyr main will complain if zephyr.h is
used but CONFIG_LEGACY_INCLUDE_PATH disabled.
This patch deprecates zephyr.h and uses kernel.h instead,
so that we don't break with latest zephyr.

Enable the Zephyr based mtrace backend for all Intel IPC4 platforms.
Also enable routing SOF logs to Zephyr and bump the default
logging level to INFO.

Moved hardcoded cycles values for DMIC IO from dmic.h header
to per-platform configuration file (defconfig files for
non-Zephyr builds and app/boards for Zephyr builds).
Added new entry to intel drivers Kconfig - CONFIG_DMIC_HW_IOCLK.
Modification of this clock value may be used for testing purposes
like building firmware for FPGA or simulator.

Remove duplicate configs with base IPC4 overlay and add PM related
configs to be able to compile upstream Zephyr SSP changes.
Also enable ALH native driver.

The native drivers zephyr build requires significantly more configs to
be set, so add those to separate overlay. This overlay can be used with
the -o switch when using the xtensa-build-zephyr script.

Remove overlays as they are the same board configurations available in
app/.
Keep common overlays and change script to reflect those changes.

Make the main SOF app part of SOF, where it belongs. No need for any
overlays (which just duplicated the sample .conf anyways) and one place
to build everything.
This now does not depend on zephyr samples, which have a different
purpose completely.
