bf71ab8ba5 NFC: Add HCI quirks to support driver (non)standard implementations
Some chips diverge from the HCI spec in their implementation of standard
features. This adds a new quirks parameter to
nfc_hci_allocate_device() to let the driver indicate its divergence.

40d06d3647 NFC: Changed event_received hci ops result semantic
Some chips use a standard HCI event code, destined to a proprietary
gate, with a different meaning. Therefore, the HCI driver must always
have a chance to intercept the event before standard processing is
attempted.
The new semantic specifies that the result value "1" means that the
driver doesn't especially handle the event. result <= 0 means it was
handled.

27c31191b3 NFC: Added error handling in event_received hci ops
There is no use to return an error if the caller doesn't get it.

61cdb01853 NFC: Move pn544.h to linux/platform_data/
The pn544.h just provides the platform data struct and defines and
nothing else. So move it to to linux/platform_data/ now.

97f18414af NFC: Separate pn544 hci driver in HW dependant and independant parts
The driver now has all HCI stuff isolated in one file, and all the
hardware link specifics in another. Writing a pn544 driver on top of
another hardware link is now just a matter of adding a new file for that
new hardware specifics.
