When the EC is busy enough to start missing RX characters an ORECF might come (Overrun error), we never check for this bit, so that means the interrupt handler will be called in a loop because it never clears that bit. This disables the overrun detection feature. BUG=chrome-os-partner:33451 TEST=get firmware to poll the EC for keyboard presses, type really fast on the keyboard, note how system does not watchdog reset anymore but loses the occasional character instead.
