Resetting the EC after reflashing LinuxBIOS

[Mitch Bradley]

Quanta engineers walked me through the reset and write protect logic and 
convinced me that it works correctly.

EC command 0x05 (sent via the port 68/6c pair) will cause the EC to 
reset itself and the rest of the system, in the process releasing the 
write protect latch.

A note about reading the Quanta schematics: They use "*" instead of e.g. 
"NOPOP" for components that are not normally loaded .  One such 
component had me mightily confused about how the write protect latch 
works, until their notation was pointed out to me.
