01d719a228 NFC: Add ISO 14443 type B protocol
Some devices (e.g. Sony's PaSoRi) can not do type B polling, so we have
to make a distinction between ISO14443 type A and B poll modes.

1195d89b2d NFC: Download TI NFC init script
Download TI NFC init script during nfcwilink open operation,
after the NFC channel is registered with TI shared transport.
TI NFC init script is written in BTS format.
First, read the chip version via a special vendor specific command.
Second, we request the relevant BTS file from the user space, and
then send the BTS commands to the chip.

baf79c33e2 drivers/nfc: add module.h to nfcwilink.c
This is a full module, with module_init() and module_exit() and
so it needs module.h called out for inclusion.
