I've received the result that from one of my partners this patch doesn't work properly
and the platform doesn't go into a lower power state.  (The patch submitted by KH/me
did work on said system to get it into a lower power state for them).

This was not a disk with HMB, but with regard to the HMB I believe it needs to be
removed during s0ix so that there isn't any mistake that SSD thinks it can access HMB
memory in s0ix.
