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.

Some NFC chips will statically create and open pipes for both standard
and proprietary gates. The driver can now pass this information to HCI
such that HCI will not attempt to create and open them, but will instead
directly use the passed pipe ids.

If "buf[0]" is 255 then "len" gets set to 0. The call to
"crc_ccitt(0xffff, buf, len - 2);" casts the "len - 2" to a high
positive number which is ugly.

This is an NFC driver for NXP pn544.
Unlike pn544.c, this one is based on the NFC HCI and SHDLC kernel layers.
