NFC: Implement NCI dep_link_up and dep_link_down
During NFC-DEP target activation, store the remote general bytes to be used later in dep_link_up. When dep_link_up is called, activate the NFC-DEP target, and forward the remote general bytes. When dep_link_down is called, deactivate the target. Signed-off-by: Ilan Elias <ilane@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
