[PATCH v2 3/4] powerpc: replace vga_fixup() with generic code

Currently, we do a PCI fixup to mark a default card so that Xorg
autoconfiguration works.
There is a new generic method to do this sort of vga fixup.
Code-wise, it is identical, however instead of firing at the
FIXUP_FINAL stage it fires at the FIXUP_ENABLE stage. This means
a card will not be marked as default unless a driver enables it.

Tested with xeyes on qemu TCG, which does use this code path.
