Minimal support for viafb suspend/resume
This patch adds minimal support for suspend/resume of the
VIA framebuffer device. It requires a version of OFW
that restores the video mode.
This patch is OLPC-specific as the proper upstream solution
is to move the VIA video path to using the kernel modesetting
infrastructure and doing a proper save/restore in the kernel.
