NFC: 3.20 second pull request

This is the second NFC pull request for 3.20.

It brings:

- NCI NFCEE (NFC Execution Environment, typically an embedded or
  external secure element) discovery and enabling/disabling support.
  In order to communicate with an NFCEE, we also added NCI's logical
  connections support to the NCI stack.

- HCI over NCI protocol support. Some secure elements only understand
  HCI and thus we need to send them HCI frames when they're part of
  an NCI chipset.

- NFC_EVT_TRANSACTION userspace API addition. Whenever an application
  running on a secure element needs to notify its host counterpart,
  we send an NFC_EVENT_SE_TRANSACTION event to userspace through the
  NFC netlink socket.

- Secure element and HCI transaction event support for the st21nfcb
  chipset.
