Add new public functions to grab information in string format:

- New nfc_device_get_information_about()
 - Moved nfc-utils function str_nfc_baud_rate()
 - New str_nfc_modulation_type()
 - Add new device_get_information_about callback to nfc_driver struct
 - Export new symbols
 - Changed internal pn53x firmware text handling: we now store firmware text for further operations
 - print_nfc_target() now uses str_nfc_* functions
 - nfc-probe util now have a verbose which display information on detected devices (Fix verbose set but not used warning ;-) )
