Follow reef setting.
This patch changes the entry/exit model for S0ix from a PCH
SLP_S0 signal based model to a hybrid host event/direct interrupt
model. The kernel will send host events on kernel freeze/thaw exit;
EC will initiate the S0ix entry based on host command and exit via
another host command from kernel.
The assertion of SLP_S0 comes later than HC(suspend) and deasserion
of SLP_S0 comes earlier than HC(resume).
