applying rwkv6.cu to VisualRWKV-v6

[ddddewang0425]

Hello. I try to apply rwkv6.cu to VisualRWKV-v6 in order to reuse last state.
there is no state saving operation in the visualRWKV-v6..
But, I don't know how can I use rwkv6.cu in the visualRWKV-v6 becuase there is no backward operation in rwkv6.cu.
Could you help me?
