map only the apertures, and use the same handle for framebuffer

This patch works on my TwisterK but apparently not on some other cards. Since
the first apertures should provide a linear mapping of the framebuffer there is
no need for a separate framebuffer DRM map, and only the apertures need to be
mapped. The aperture DRM map handle can then be used as framebuffer handle as
well.

Probably not the final patch, but I will just attach it here for reference.
