NFC: 3.16: First pull request

Browse source 
This is the NFC pull request for 3.16. We have:
 
 - STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
   thus relies on the HCI stack. This submission provides support for tag
   redaer/writer mode (including Type 5) and device tree bindings.
 
 - PM runtime support and a bunch of bug fixes for TI's trf7970a.
 
 - Device tree support for NXP's pn544. Legacy platform data support is
   obviously kept intact.
 
 - NFC Tag type 4B support to the NFC Digital stack.
 
 - SOCK_RAW type support to the raw NFC socket, and allow NCI
   sniffing from that. This can be extended to report HCI frames and also
   proprietarry ones like e.g. the pn533 ones.
