drm/i915/gvt: Drop redundant prepare_write/pin_pages

Browse source

Since gvt calls pin_map for the shadow batch buffer, this makes the
action of prepare_write [+pin_pages] redundant. We can write into the
obj->mm.mapping directory and the flush_map routine knows when it has to
flush the cpu cache afterwards.
