nfc: constify nfc_llc_ops
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. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The llc must be registered with nfc before it can be used. Do that by
calling::
- nfc_llc_register(const char *name, struct nfc_llc_ops *ops);
+ nfc_llc_register(const char *name, const struct nfc_llc_ops *ops);
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.
