board/nvidia/bf3: set eth names according to doc

Browse Source 
Set the names of the Ethernet interfaces that are exposed from a first
boot so they are aligned with those described by Mellanox/NVIDIA
documentation for the BF3.

Those tmfifo and oob interface names are describeded at:
  https://docs.nvidia.com/networking/display/bluefielddpuosv460/host-side+interface+configuration

When running the native Ubuntu on the BF3 board, the following udev
rules are set:
$ cat /etc/udev/rules.d/91-tmfifo_net.rules
SUBSYSTEM=="net", ACTION=="add", DEVPATH=="/devices/platform/MLNXBF01:00/virtio1/net/eth[0-9]", NAME="tmfifo_net0"

$ cat /etc/udev/rules.d/92-oob_net.rules
SUBSYSTEM=="net", ACTION=="add", DEVPATH=="/devices/platform/MLNXBF17:00/net/e*", NAME="oob_net0", RUN+="/sbin/sysctl -w net.ipv4.conf.oob_net0.arp_notify=1"

The default CX ports of the BF3 are:
ubuntu@bf$ ip link show p0
4: p0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode
   DEFAULT group default qlen 1000
    link/ether a0:88:c2:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    altname enp3s0f0np0
ubuntu@bf$ ip link show p1
5: p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode
   DEFAULT group default qlen 1000
    link/ether a0:88:c2:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    altname enp3s0f1np1
