The VCMDQ in the tegra241-cmdqv driver has a guest mode that supports only a few invalidation commands. A batch is initialized with a cmdq, so it has to confirm whether a new command is supported or not. Add a supports_cmd function pointer to the cmdq structure, where the vcmdq driver should hook a command scan function. Add an inline helper too so it can be used by both sides. If a new command is not supported, simply issue the existing batch and re- init it as a new batch. Signed-off-by:
