[dpdk-dev] [PATCH v2 10/10] doc: refer PMD compile and test section from thunderx doc

Refer the section which explains driver compilation and running of
testpmd in Linux, instead of describing it in driver documentation.

-Running testpmd
-~~~~~~~~~~~~~~~
-
-This section demonstrates how to launch ``testpmd`` with ThunderX NIC VF device
-managed by ``librte_pmd_thunderx_nicvf`` in the Linux operating system.
-
-#. Load ``vfio-pci`` driver:
-
-   .. code-block:: console
-
-      modprobe vfio-pci
-
-   .. _thunderx_vfio_noiommu:
-
-#. Enable **VFIO-NOIOMMU** mode (optional):
-
-   .. code-block:: console
-
-      echo 1 > /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
-
-   .. note::
-
-      **VFIO-NOIOMMU** is required only when running in VM context and should not be enabled otherwise.
-      See also :ref:`SR-IOV: Prerequisites and sample Application Notes <thunderx_sriov_example>`.
-
-#. Bind the ThunderX NIC VF device to ``vfio-pci`` loaded in the previous step:
-
-   Setup VFIO permissions for regular users and then bind to ``vfio-pci``:
-
-   .. code-block:: console
-
-      ./usertools/dpdk-devbind.py --bind vfio-pci 0002:01:00.2
-
-#. Start ``testpmd`` with basic parameters:
-
-   .. code-block:: console
-
-      ./arm64-thunderx-linuxapp-gcc/app/testpmd -l 0-3 -n 4 -w 0002:01:00.2 \
