Add PN533 based NFC devices

Workaround PN533 USB descriptor corruption

During normal operation, the PN533 chip may corrupt its USB configuration,
interface and endpoint descriptors. The device descriptor remains unaffected.

Since the descriptors are documented to be immutable, we can work around
the problem by providing hard-coded descriptors instead of pulling them
from the device.

Userland implementation such as NFC tools' libnfc use the same approach,
but this kernel quirk is still necessary so that the device can be
attached on reboot, after its USB descriptors got corrupted.
