drm/nouveau: fix init with agpgart-uninorth
commit eda85d6ad490923152544fba0473798b6cc0edf6 upstream.
Check that the AGP aperture can be mapped. This follows a similar change
done for Radeon (commit 365048ff, drm/radeon: AGP memory is only I/O if
the aperture can be mapped by the CPU.).
The patch fixes the following error seen on G5 iMac:
nouveau E[ DRM] failed to create kernel channel, -12
