Ranjani Sridharan bf7aa04890 mixout: Convert component to use the module adapter 
Convert the mixout module to use the module adapter. The
bind/unbind/get_attribute ops in the mixout module have been moved to the
module_adapter ops and is functionally the same as with the comp_drv
ops.

The struct mixout_data struct has been simplified to contain 2 fields as
the source info table has been moved to struct processing_module and
rename the consumed_yet_not_produced_frames field in struct mixout_data
to pending_frames.

README 

SOF with Zephyr RTOS
====================

SOF currently uses the Cadence Xtos/HAL and it's own kernel functions as
its RTOS. SOF is moving to use Zephyr as it's RTOS in parallel to current
releases using xtos.

The initial "alpha" of SOF on Zephyr will use the Zephyr RTOS for boot, IRQs,
scheduling and memory allocation. Subsequent release will use more Zephyr
functionality as code is moved from SOF to Zephyr (i.e. EDF scheduler updates
copied from SOF to Zephyr).

Building SOF on Zephyr
======================

Section promoted to
https://thesofproject.github.io/latest/getting_started/build-guide/build-with-zephyr.html

Testing on Qemu
===============

Get the SOF qemu sof-v4.2 branch here.

git@github.com:thesofproject/qemu.git

Configure as

./configure' '--prefix=.' '--target-list=xtensa-softmmu,x86_64-softmmu' \
             '--enable-gtk' '--enable-sdl' '--enable-spice' \
             '--audio-drv-list=alsa' '--enable-libusb' \
             '--enable-usb-redir' '--enable-coroutine-pool' \
             '--disable-opengl' '--enable-fdt'

 Then run make.

FW can be tested as follows using the qemu helper script.

 ./xtensa-host.sh apl \
     -r ../../sof/sof/build_apl_gcc/src/arch/xtensa/rom-apl.bin \
     -k ../../zephyrproject/zephyr/build/zephyr/zephyr.ri

Where -r and -k are used to specify the ROM and kernel files.

The ROMS can be built from the SOF repo by running

./scripts/xtensa-build-all.sh  -r -a

Using console
-------------

Using logging and simulator backend with processing printk (LOG_PRINTK)
can bring console in qemu.

 - Enable xtensa simulator logging backend (LOG_BACKEND_XTENSA_SIM).
 - Enable printk processing(LOG_PRINTK)
 - Add "-semihosting" to qemu command line. Make sure it goes through scripts to real qemu.
