NFC: nci: Add management for NCI state for machine rf_deactivate_ntf
A notification for rf deaction can be IDLE_MODE, SLEEP_MODE, SLEEP_AF_MODE and DISCOVERY. According to each type and the NCI state machine is different (see figure 10 RF Communication State Machine in NCI specification) Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
