x86, olpc: Add XO-1 SCI driver and power button control
The System Control Interrupt is used in the OLPC XO-1 to control various features of the laptop. Add the driver base and the power button functionality. This driver can't be built as a module, because functionality added in future patches means that some drivers need to know at boot-time whether SCI-based functionality is available.
