    boot - Bring in fix for qemu menu time bug
    
    * qemu does not debounce the RTC data.  The RTC chip uses a serial interface
      as well as a simple carry propagation incremenber which can catch
      transitions in the middle of an update, resulting in corrupted data.
    
    * Simply requery the time until a stable value is found.
