S0ix: use both SLP_S0 interrupt and host command for s0ix
EC currently uses a host command from kernel to enter s0ix.
This patch waits for the SLP_S0 interrupt to come after receiving
the host command before entering S0ix.
On the exit path, the SLP_S0 interrupt directly triggers the
exit rather than waiting for the host command.
BRANCH=none
BUG=b:37443151
TEST=check in EC logs for SLP_S0 entry and powerindebug output,
check suspend_stress_test on reef and soraka works fine,
make -j8 buildall runs fine
