====================
NFC 4.2 pull request

This is the NFC pull request for 4.2.

- NCI drivers can now define their own handlers for processing
  proprietary NCI responses and notifications.

- NFC vendors can use a dedicated netlink API to send their own
  proprietary commands, like e.g. all commands needed to implement
  vendor specific manufacturing tools.

- A new generic NCI over UART driver against which any NCI chipset
  running on top of a serial interface can register.

- The st21nfcb driver is renamed to st-nci as it can and will support
  most of ST Microelectronics NCI chipsets.

- The st21nfcb driver can put its CLF in hibernate mode and save
  significant amount of power.

- A few st21nfcb minor fixes.

- The NXP NCI driver now supports ACPI enumeration.

- The Marvell NCI driver now supports both USB and serial
  physical interfaces.

- The Marvell NCI drivers also supports NCI frames being muxed
  over HCI. This is a setting that can be defined by a DT property.
