doc: nrf70: enterprise: Point to the upstream docs

Upstream already has the proper instructions, so, remove duplication and
point to the upstream docs.

 This mode uses the Extensible Authentication Protocol (EAP) with Transport Layer Security (TLS) for authentication.
 The client and the authentication server exchange certificates to authenticate each other.

-Enterprise testing: X.509 certificate headers generation
-========================================================
-
-Wi-Fi enterprise security requires use of X.509 certificates.
-Test certificates in PEM format are available at :zephyr_file:`samples/net/wifi/test_certs/` repository.
-During the build process, the certificates are converted to a C header file that is included in the Wi-Fi shell module or the :ref:`Wi-Fi credentials <lib_wifi_credentials>` library.
-
-To use custom certificates, use the following commands:
-
-.. code-block:: bash
-
-    $ cp client.pem samples/net/wifi/test_certs/
-    $ cp client-key.pem samples/net/wifi/test_certs/
-    $ cp ca.pem samples/net/wifi/test_certs/
-    $ cp client.pem samples/net/wifi/test_certs/client2.pem
-    $ cp client-key.pem samples/net/wifi/test_certs/client-key2.pem
-    $ cp ca.pem samples/net/wifi/test_certs/ca2.pem
-
-    $ west build -p -b <board> samples/net/wifi -- -DEXTRA_CONF_FILE=overlay-enterprise.conf
-
-.. note::
-     The EAP phase2 certificates (suffixed with 2) are unused in ``WPA2-EAP-TLS`` but are mandatory for building the sample application.
-     The phase1 certificates are copied as phase2 certificates to avoid build errors as a temporary workaround.
-
-To establish a Wi-Fi connection, use the following command:
-
-.. code-block:: console
-
-    uart:~$ wifi connect -s <SSID> -k 7 -a anon -K <key passphrase>
-
-.. code-block:: console
-
-   uart:~$ wifi_cred add -s <SSID> -k 7 -a anon -K <key passphrase>
-
-
-.. note::
-
-      The Wi-Fi credentials only support 16characters for the anonymous identity and the key passphrase.
-
-The server certificate is also provided in the same directory for testing purposes.
-You can use any AAA server for testing purposes, such as FreeRADIUS or hostapd.
-
-.. note::
-
-    The certificates are for testing purposes only and should not be used for production.
