The latest AMD processors include additional IP blocks that must be turned
off before transitioning to low power. PMFW provides an interface to
retrieve debug information from each IP block, which is useful for
diagnosing issues if the system fails to enter or exit low power states,
or for profiling which IP block takes more time. Add support for using
this information within the driver.
