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.

Add the ability to select between multiple targets in NCI.
If only one target is found, it will be auto-activated.
If more than one target is found, then DISCOVER_NTF will be
generated for each target, and the host should select one by
calling DISCOVER_SELECT_CMD. Then, the target will be activated.
If the activation fails, GENERIC_ERROR_NTF is generated.

This is required in order to support more NCI states (e.g.
for multiple targets support).
