[PATCH v4 2/3] drm/ast: use DRM_GEM_SHMEM_SIMPLE_DRIVER_OPS

[oushixiong1025 at 163.com]

From: Shixiong Ou <oushixiong at kylinos.cn>

Import dmabuf without mapping its sg_table to avoid issues likes:
  ast 0000:07:00.0: swiotlb buffer is full (sz: 3145728 bytes), total 32768 (slots), used 0 (slots)
