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.

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.
