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
