drm/nv40: attempt to reserve just enough vram for all 32 channels
This also makes the fact we're giving 512MiB of GART space to all PCIE boards explicit, although the vast majority (if not all) of them will now have a ramin_rsvd_vram larger than 2MiB anyway. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
