pinctrl: Check requested IP in DHCPREQUEST messages
See RFC 2131, section 4.3.2. When handling a DHCPREQUEST message, the
server should validate that the client's requested IP matches the
offered IP. If not, the server should reply with a DHCPNAK. The client's
requested IP is either specified as the Requested IP Address (option
50), or as the ciaddr, depending on the client's state.
