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

This patch fixes https://bugs.freedesktop.org/show_bug.cgi?id=58806.
For some (weird) reason Nouveau worked on this configuration on 3.6 kernel,
so cc'ing stable@vger seems to be appropriate.

Cool I've picked this up and applied it for stable into fixes now.
