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.

x86, olpc: Add XO-1 suspend/resume support

Add code needed for basic suspend/resume of the XO-1 laptop.
Based on earlier work by Jordan Crouse, Andres Salomon, and others.

This patch incorporates all earlier feedback from Thomas Gleixner. To
clarify a certain point (now more obvious in the code itself):
On resume, OpenFirmware returns execution to Linux in protected mode
with a kernel-compatible GDT already set up. The changes and
simplifications suggested have all been included.

x86, olpc: Rename olpc-xo1 to olpc-xo1-pm

Based on earlier review comments, we'll no longer try to stick all of
our XO-1 goodies in a single driver. We'll split it into a power management
driver, and an EC/SCI driver.

As a first step, rename olpc-xo1 to olpc-xo1-pm, and make it builtin
instead of modular.
