dma-buf: rk_heaps: set name for dmabuf to debug

Browse Source 
The rk_dma_heap_bufferfd_alloc has expand argument 'const char *name'
which is used for debug to oversee all dmabuf.

The dma_buf_set_name is provided and exported by dma-buf, also support
via ioctl of dma-buf. This patch set the name to dmabuf if support for
the CONFIG_DMABUF_RK_HEAPS_DEBUG.
