[BUG] [ADL][ZEPHYR] failed to enable target core for widget SSP0.OUT on ADLP ZEPHYR platform

[keqiaozhang]

Describe the bug
When playing audio on adlp zephyr platform, it runs to:

[  126.590714] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x40070000 (msg/reply size: 12/12): -22

[  126.590750] kernel: sof-audio-pci-intel-tgl 0000:00:1f.3: error: failed setting up DAI widget SSP0.OUT

[  126.590780] kernel:  NoCodec-0: ASoC: soc_pcm_hw_params() failed (-22)
[  126.590792] kernel:  Port0: ASoC: dpcm_fe_dai_hw_params failed (-22)

After debugging, this regression is related to recently tplg changes(multi-core enabling).

To Reproduce
aplay -Dhw:0,0 -r 48000 -c 2 -f S16_LE /dev/zero -vvv

Expected behavior
no ipc error

Zephyr is currently limited to using 2 cores on Intel ADSP, this should be eliminated when zephyrproject-rtos/zephyr#39603 is merged

[XiaoyunWu6666]

FYI , though zephyrproject-rtos/zephyr#39603 has been merged
in inner daily test 8518
on model ADLP_RVP_NOCODEC_ZEPHYR
in testcase check-alsabat-headset-playback
still failed to enable target core for widget SSP0.OUT

@kv2019i I assume we are bringing up the target core after core 0 is fully booted. @andyross is asynchronous secondary core booting/power off supported today or still WIP for some platforms ?

[kv2019i]

There's first a simple problem that the core count default is 2 on Zephyr side. That is easy to fix. But with that done, we are seeing some weird errors. With a topology with four PCM pipelines assigned to cores 0, 1, 2 and 3, tests works ok on cores 0 and 3, but the secondary boot fails on cores 1 and 2. Debugging continues. This should be supported in both Zephyr and SOF.

[kv2019i]

Not a complete fix, but gets us further along: https://github.com/kv2019i/zephyr/pull/new/topic/cavs25-4cores-default

@lgirdwood More issues found, maybe we need to move this to v2.1? New issue #5050
