"NFC: 3.18 pull request

This is the NFC pull request for 3.18.

We've had major updates for TI and ST Microelectronics drivers:

For TI's trf7970a driver:

- Target mode support for trf7970a
- Suspend/resume support for trf7970a
- DT properties additions to handle different quirks
- A bunch of fixes for smartphone IOP related issues

For ST Microelectronics' ST21NFCA and ST21NFCB drivers:

- ISO15693 support for st21nfcb
- checkpatch and sparse related warning fixes
- Code cleanups and a few minor fixes

Finally, Marvell add ISO15693 support to the NCI stack, together with a
couple of NCI fixes."
