We can't pass devm_ allocated pointers to kfree() because they will be
freed again after the drive is unloaded.

Correctly call nfc_set_parent_dev before nfc_register_device.
Otherwise the driver will OOPS when being removed.

The driver now has all core stuff isolated in one file, and all
the hardware link specifics in another. Writing a pn533 driver
on top of another hardware link is now just a matter of adding a
new file for that new hardware specifics.
The first user of this separation will be the i2c based pn532
driver that reuses pn533 core implementation on top of an i2c
layer.
