Russell King 43659222e7 ARM: footbridge: fix VGA initialisation 
It's no good setting vga_base after the VGA console has been
initialised, because if we do that we get this:

Unable to handle kernel paging request at virtual address 000b8000
pgd = c0004000
[000b8000] *pgd=07ffc831, *pte=00000000, *ppte=00000000

which is an access to the 0xb8000 without the PCI offset required to
