[Nouveau] [PATCH] drm/nouveau: enlarge GART aperture

[Luca Barbieri]

This patch enlarges the PCI GART aperture to 512 MB.

The current 64MB aperture is too small and should be enlarged.
The optimal amound may be card/system-dependent, so a more sophisticated
approach may be preferable.
In particular, if RAMIN is less than 1MB, a 512MB aperture won't fit.
