Resurrect the "park APs in realmode" idea that we explored back at t2k13
(and which didn't work at that time due to a bug which has since been
fixed). The APs are now demoted to real mode and placed in a HLT loop
while the hibernated image is being unpacked.

Helps my x230 significantly, no more spurious reboots on resume.
