* venc_if_init - Create the driver handle
Frame-racing mode encoding need more venc working buffers, it will break the compatibility if we just add venc_vsi in AP-Kernel but not in firmware, so add a new venc driver interface to distinguish the sigle_core_mode and frame_racing mode. The new driver interface can be used for different codecs in the future.
