====================
NFC 4.7 pull request

This is the first NFC pull request for 4.7. With this one we
mainly have:

- Support for NXP's pn532 NFC chipset. The pn532 is based on the same
  microcontroller as the pn533, but it talks to the host through i2c
  instead of USB. By separating the pn533 driver into core and PHY
  parts, we can not add the i2c layer and support the pn532 chipset.

- Support for NCI's loopback mode. This is a testing mode where each
  packet received by the NFCC is sent back to the DH, allowing the
  host to test that the controller can receive and send data.

- A few ACPI related fixes for the STMicro drivers, in order to match
  the device tree naming scheme.

- A bunch of cleanups for the st-nci and the st21nfca STMicro drivers.
