Poppy: Enter/exit from S0ix based on host commands from kernelstabilize-9428.B
This patch enables the entry/exit model for S0ix based on host
commands. 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.
BRANCH=none
BUG=b:36630881
TEST=Build/flash EC and check 'echo freeze > /sys/power/state'
command in OS shell. Verify EC goes to S0ix state, and on wake
it comes back to S0 state.
