This is the first NFC pull request for 3.14

Browse source 
It includes:
 
 * A new NFC driver for Marvell's 8897, and a few NCI fixes and
   improvements needed to support this chipset.
 
 * An LLCP fix for how we were setting the default MIU on a p2p link. If
   there is no explicit MIU extension announced at connection time, we
   must use the default one and not the one announced at LLCP link
   establishement time.
 
 * A pn544 EEPROM config update. Some of the currently EEPROM configured
   values are overwriting the firmware ones while other should not be set
   by the driver itself.
 
 * Some NFC digital stack fixes and improvements. Asynchronous functions
   are better documented, RF technologies and CRC functions are set upon
   PSL_REQ reception, and a few minor bugs are fixed.
 
 * Minor and miscelaneous pn533, mei_phy and port100 fixes.
