NFC: nci: Move NFCEE discovery logic
NFCEE_DISCOVER_CMD is a specified NCI command used to discover NFCEE IDs. Move nci_nfcee_discover() call to nci_discover_se() in order to guarantee: - NFCEE_DISCOVER_CMD run when the NCI state machine is initialized - NFCEE_DISCOVER_CMD is not run in case there is not discover_se hook defined by a NFC device driver.
