[PATCH 05/10] NFC: hci: Add cmd_received handler

[Christophe Ricard <christophe.ricard-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

When a command is received, it is sometime needed to let the CLF driver do
some additional operations. (ex: count remaining pipe notification...)

Make also generic HCI commands available to other NFC drivers
