Google/Snow: Enable suspend/resume.
Add the suspend/resume feature into bootblock and romstage.
Note, resuming with X and touchpad driver may be still unstable.
Verified by building and booting successfully on Google/Snow, and then executing
the "suspend_stress_test" in text mode ("stop ui; suspend_stress_test") in
Chromium OS, passed at least 20 iterations.
