** Function         NFA_Enable
**
** Description      This function enables NFC. Prior to calling NFA_Enable,
**                  the NFCC must be powered up, and ready to receive commands.
**                  This function enables the tasks needed by NFC, opens the NCI
**                  transport, resets the NFC controller, downloads patches to
**                  the NFCC (if necessary), and initializes the NFC subsystems.
**
**                  This function should only be called once - typically when NFC
**                  is enabled during boot-up, or when NFC is enabled from a
**                  settings UI. Subsequent calls to NFA_Enable while NFA is
**                  enabling or enabled will be ignored. When the NFC startup
**                  procedure is completed, an NFA_DM_ENABLE_EVT is returned to the
**                  application using the tNFA_DM_CBACK.

** Function         NFA_RegisterNDefTypeHandler
**
** Description      This function allows the applications to register for
**                  specific types of NDEF records. When NDEF records are
**                  received, NFA will parse the record-type field, and pass
**                  the record to the registered tNFA_NDEF_CBACK.
**
**                  For records types which were not registered, the record will
**                  be sent to the default handler. A default type-handler may
**                  be registered by calling this NFA_RegisterNDefTypeHandler
**                  with tnf=NFA_TNF_DEFAULT. In this case, all un-registered
**                  record types will be sent to the callback. Only one default
**                  handler may be registered at a time.
**
**                  An NFA_NDEF_REGISTER_EVT will be sent to the tNFA_NDEF_CBACK
**                  to indicate that registration was successful, and provide a
