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.

Adding the dependency seems like a more reasonable thing compared to ifdef-ing the bits, as if one has an XO-1.75 they almost certainly want a baterry and AC adapter support.

Include support for the OLPC XO Embedded Controller (EC). The EC
provides various platform services, including support for the power,
button, restart, shutdown and battery charging status.
Unless you have an OLPC XO laptop, you will want to say N.
