xen: allow enable use of VGA console on dom0
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 ]

[v1: Rebased on 2.6.39]
[v2: Removed incorrect comments and fixed compile warnings]
