xen: allow enable use of VGA console on dom0
commit c2419b4a4727f67af2fc2cd68b0d878b75e781bb upstream.
Get the information about the VGA console hardware from Xen, and put
it into the form the bootloader normally generates, so that the rest
of the kernel can deal with VGA as usual.
[ Impact: make VGA console work in dom0 ]
