platform/chrome: cros_ec_lpc: Move host command to prepare/complete
Update cros_ec_lpc_pm_ops to call cros_ec_lpc_prepare() during PM .prepare() and cros_ec_lpc_complete() during .complete(). This moves the host command that the AP sends and allows the EC to log entry/exit of AP's suspend/resume more accurately.
