NFC 4.7 pull request

Browse source 
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.
