NFC: 3.20 first pull request

This is the first NFC pull request for 3.20.

With this one we have:

- Secure element support for the ST Micro st21nfca driver. This depends
  on a few HCI internal changes in order for example to support more
  than one secure element per controller.

- ACPI support for NXP's pn544 HCI driver. This controller is found on
  many x86 SoCs and is typically enumerated on the ACPI bus there.

- A few st21nfca and st21nfcb fixes.
