Subject: [PATCH 2/2] ASoC: fsl_mqs: Add i.MX95 platform support
On i.MX95 there are two MQS instances, so "fsl,mqs-ctrl"
need to be used to distinguish them. Only can list the
settings of one instance in soc data.
As "fsl,mqs-ctrl" is optional, if this property does not exist,
the driver will use soc data to configure the MQS module.
On i.MX95 one instance in wakeup-mix is supported by this
commit, another instance in always-on-mix is not supported,
which depends on System Manager function readiness, but it
can also benefit from the new property.
