x86, olpc: Register XO-1 platform devices
The upcoming XO-1 rfkill driver (for drivers/platform/x86) will register itself with the name "xo1-rfkill", and the already-merged XO-1 poweroff code uses name "olpc-xo1" Add the necessary mechanics so that these devices are properly initialized on XO-1 laptops.
