drm/bochs: fix bochs_gem_prime_mmap
ttm_fbdev_mmap() just doesn't work. It appears to work fine, mmap()
returns success, but any attempt to actually access the mapping causes a
SIGBUS.
We can just use drm_gem_prime_mmap() instead. Almost. We have to copy
over the start offset from the ttm_buffer_object vm_node to the
drm_gem_object vm_node so the offset math in drm_gem_prime_mmap() works
correctly for us even though we use ttm to manage our objects.
