net/iavf: remove i40evf devargs option

Browse Source 
Due to i40evf will be removed, so there's no need to keep the devargs
option "driver=i40evf" in iavf.

@ -88,12 +88,6 @@ For more detail on SR-IOV, please refer to the following documents:
assignment in hypervisor. Take qemu for example, the device assignment should carry the IAVF device id (0x1889) like
``-device vfio-pci,x-pci-device-id=0x1889,host=03:0a.0``.
Starting from DPDK 21.05, the default VF driver for Intel® 700 Series Ethernet Controller will be IAVF. No new feature
will be added into i40evf except bug fix until it's removed in DPDK 21.11. Between DPDK 21.05 and 21.11, by using the
``devargs`` option ``driver=i40evf``, i40evf PMD still can be used on Intel® 700 Series Ethernet Controller, for example::
-a 81:02.0,driver=i40evf
When IAVF is backed by an Intel® E810 device, the "Protocol Extraction" feature which is supported by ice PMD is also
available for IAVF PMD. The same devargs with the same parameters can be applied to IAVF PMD, for detail please reference
the section ``Protocol extraction for per queue`` of ice.rst.
