Description

xen: fetch dom0 video console information from Xen

It's possible for Xen to switch the video mode set by the boot loader,
so that the information passed in the kernel metadata is no longer
valid. Fetch the video mode used by Xen using an hypercall and update
the medatada for the kernel to use the correct video mode.
