Subject: [PATCH] ASoC: SOF: sof_ipc_pm_ops: Add support for DSP core power management
Git-commit: b41252d8820c7009078c3d401a807a9da899075f
Patch-mainline: v6.0-rc1
References: jsc#PED-850

Add a new ops for handling DSP core power state which can be used to tell
the DSP to turn on/off a core (or to inform it that a core is going to be
turned on/off if the core is host managed).
