chromeec: Clear post code before reboot to RO

When doing an EC requested reboot to RO mode clear the
    saved post code in order to prevent confusing events in
    the log where the system is rebooted intentionally.

BUG=chrome-os-partner:28234
    BRANCH=none
    TEST=build and boot on samus, run FAFT, check for odd
    eventlog entries about last post code 0x31 when it is
    rebooted during samus romstage entry point.
