Add a bit for indicating support multi-core encoding, because multi-core encoding need more working buffers for encoder hardware. The working buffers are allocated from kernel side then pass to scp firmware side through shared memory, the struct definition must be kept align between kernel and scp firmware side. New another shared memory struct for multi-core encoding.
