The workarounds introduced in the three patches starting at 888eafa00b99aa06b4ff688407336811a7ff439a assumed that any powerdown request will be (forced to be) terminal. This assumption can no longer be the case for new CPUs so there is a need to revisit these older cores. Since we may wake up, we now need to respect the workaround's recommendation that the workaround needs to be reverted on wakeup. So do exactly that.
Introduce a new helper to toggle bits in assembly. This allows us to call the workaround twice, with the first call setting the workaround and second undoing it. This is also used for gelas' an travis' powerdown routines. This is so the same function can be called again
Also fix the condition in the cpu helper macro as it was subtly wrong
