NFC: nci: Add support for different NCI_DEACTIVATE_TYPE

nci_rf_deactivate_req only support NCI_DEACTIVATE_TYPE_IDLE_MODE.
In some situation, it might be necessary to be able to support other
NCI_DEACTIVATE_TYPE such as NCI_DEACTIVATE_TYPE_SLEEP_MODE in order for
example to reactivate the selected target.
