Core power up involves 2 steps: The first step tries to
power up the core by setting the ADSPCS.SPA bit for the host-managed
cores. The second step involves sending the IPC to power up other
cores that are not host managed. The enabled_cores_mask should
be updated only when both these steps are successful. If the
IPC to the DSP fails, the host-managed core that was powered in
step 1 should be powered off before returning the error.

snd_soc_find_dai() will be used from (X) CPU/Codec/Platform driver with
mutex lock, and (Y) Card driver without mutex lock.
This snd_soc_dai_link_set_capabilities() is for Card driver,
this means called without mutex.
This patch adds snd_soc_find_dai_with_mutex() to solve it.

Changing filter type without disabling codec results in filter
malfunction. Disable codec when changing filter type.

While the driver waits for DAIs to be probed and retries probing,
have the error messages at debug level instead of error.
