The IPC ops are optional, but they require that the ops struct is to be allocated with all callbacks set to NULL.
Update the code to extend the optionality to: sdev->ipc == NULL sdev->ipc->ops == NULL sdev->ipc->ops->[ops_group] == NULL sdev->ipc->ops->[pcmops_group]->ops == NULL (treated optional currently)
