NFC: digital: Add NFC-DEP Target-side ATN Support
When an NFC-DEP target receives an ATN PDU, its supposed to respond with a similar ATN PDU. When the Target receives an I PDU with the PNI one less than the current PNI and the last PDU sent was an ATN PDU, the Target is to resend the last non-ATN PDU that it has sent. This is described in section 14.12.3.4 of the NFC Digital Protocol Spec. The digital layer's NFC-DEP code doesn't implement this so add that support.
