chromeos/cr50_enable_update.c: Clear EC AP_IDLE flag
When AP boots up after Cr50 firmware update and reboot, AP finds that Cr50 reset is required for Cr50 to pick the new firmware so it trigger Cr50 reset and power off the system, AP expects system will power on automatically after Cr50 reset. However this is not the case for Chromebox, Chromebox EC set AP_IDLE flag when system is shutting down, when AP_IDLE flag is set in EC, the system stays at S5/G3 and wait for power button presssend. It cause an issue in factory that the operator needs to press power button to power on the DUT after Cr50 firmware update. This patch sends EC command to direct EC to clear AP_IDLE flag after AP shutdown so AP can boot up when Cr50 reset.
