tee: optee: Drop ffa_ops in optee_ffa structure using ffa_dev->ops directly
Now that the ffa_device structure holds the pointer to ffa_dev_ops,
there is no need to obtain the same through ffa_dev_ops_get().
Just use the ffa_dev->ops directly. Since the ffa_device itself carries
ffa_dev_ops now, there is no need to keep a copy in optee_ffa structure.
Drop ffa_ops in the optee_ffa structure as it is not needed anymore.
