drm/gma500: Pass fb_info to psb_fbdev_vm_fault()
Instead of the DRM framebuffer, pass the FB info strcuture to the
fbdev page-fault handler psb_fbdev_vm_fault(). The framebuffer is a
high-level data structure and does not belong into fault handling.
The fb_info has all necessary information. Also set fix.smem_start
to the correct value (the beginning of the framebuffer in physical
address space) and streamline the page-fault handler.
v2:
* remove unused struct drm_psb_private.fb_base (Patrik)
