From: Xiaoyong Lu <xiaoyong.lu@xxxxxxxxxxxx>
Change av1 driver to support secure video playback(svp) for
mt8188. Need to map shared memory with optee interface and
wait interrupt in optee-os.

In the original version mtk_vcodec_fw_map_dm_addr() is called before
mtk_vcodec_mem_alloc(), so if the former fails, the function terminates
early. After this patch is applied mtk_vcodec_mem_alloc() is called first and
when it is successful mtk_vcodec_fw_map_dm_addr() is called which may fail.
In case it fails maybe mtk_vcodec_mem_free() should be called before returning?
