Silicon/SynQuacer: implement 'clear NVRAM' feature using a DIP switch
Ordinary computers typically have a physical switch or jumper on the
board that allows non-volatile settings to be cleared. Let's implement
the same using DIP switch #1 on block #3, and clear the EFI variable
store if it is set to ON at boot time.
