drm/gma500/psb: Unpin framebuffer on crtc disable

commit 820de86a90089ee607d7864538c98a23b503c846 upstream.

The framebuffer needs to be unpinned in the crtc->disable callback
because of previous pinning in psb_intel_pipe_set_base(). This will fix
a memory leak where the framebuffer was released but not unpinned
properly. This patch only affects Poulsbo.
