Neither the core nor the drivers modify the passed pointer to struct
nfc_llc_ops, so make it a pointer to const for correctness and safety.

The llc must be registered with nfc before it can be used. Do that by
calling::

Again, note that the llc does not handle the physical link. It is thus very
easy to mix any physical link with any llc for a given chip driver.
