    vboot: Add support for recovery mode with forced memory retraining
    
    1. Add new function vboot_recovery_mode_memory_retrain that indicates if
    recovery mode requires memory retraining to be performed.
    2. Add helper function get_recovery_mode_retrain_switch to read memory
    retrain switch. This is provided as weak function which should be
    implemented by mainboard just like {get,clear}_recovery_mode_switch.
    
    BUG=chrome-os-partner:59352
    BRANCH=None
    TEST=Verified behavior of recovery mode with forced memory retraining on
    reef
