Subject: [PATCH] ASoC: SOF: add set_power_state() to dsp_ops for power state update
Git-commit: e8f112d8c29f44ded83f97828c104bf0904871ec
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518
D0i3 is a platform-defined substate of D0, so we need a
platform-specific callback in dsp_ops to handle the relevant
configurations.
