The framebuffer occupies the upper portion of memory (64MiB by
default), but it can only be controlled/configured via a system
mailbox or property channel (to be added by a subsequent patch).

This patch adds a virtio-vga device. It is simliar to virtio-gpu-pci,
but it also adds in vga compatibility, so guests without native
virtio-gpu support can drive the device in vga mode. It is compatible
with stdvga.

This patch adds virtio-gpu-pci, which is the pci proxy for the virtio
gpu device. With this patch in place virtio-gpu is functional. You
need a linux guest with a virtio-gpu driver though, and output will
appear pretty late in boot, once the kernel initialized drm and fbcon.
