Eric Lapuyade 9009943326 NFC: Cache the core NFC active target pointer instead of its index
The NFC Core now caches the active nfc target pointer, thereby avoiding
the need to lookup the target table for each invocation of a driver ops.
Consequently, pn533, HCI and NCI now directly receive an nfc_target
pointer instead of a target index.

Eric Lapuyade 8b8d2e08bf NFC: HCI support
This is an implementation of ETSI TS 102 622 specification.
Many NFC chipsets use HCI as the host <-> target protocol on top of a
serial link like i2c.
