NFC: Define secure element IO API and commands
In order to send and receive ISO7816 APDUs to and from NFC embedded secure elements, we define a specific netlink command. On a typical SE use case, host applications will send very few APDUs (Less than 10) per transaction. This is why we decided to go for a simple netlink API. Defining another NFC socket protocol for such low traffic would have been overengineered. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
