NFC: Allow HCI driver to pre-open pipes to some gates
Some NFC chips will statically create and open pipes for both standard
and proprietary gates. The driver can now pass this information to HCI
such that HCI will not attempt to create and open them, but will instead
directly use the passed pipe ids.
