At least on the LS1028A the crypto module is always there, but has some functions disabled on non-E parts. Thus it doesn't make sense to completely remove the node. Linux will figure out what is there and what is not.
Please note, this patch is certainly not ideal. But I don't know which processors have the SEC module always available. NXP would have to comment on that and make sure, the condition when to remove the crypto node is correct.
