Lubomir Rintel 0c3d931b3a Platform: OLPC: Add XO-1.75 EC driver 
It's based off the driver from the OLPC kernel sources. Somewhat
modernized and cleaned up, for better or worse.

Modified to plug into the olpc-ec driver infrastructure (so that battery
interface and debugfs could be reused) and the SPI slave framework.
