octeontx2-af: Configure AF VFs to talk over LBK channels
Configure AF VFs such that they are able to talk over consecutive
loopback channels.
If 8 VFs are attached to AF then communication will work as below:
TX RX
lbk0 -> lbk1
lbk1 -> lbk0
lbk2 -> lbk3
lbk3 -> lbk2
lbk4 -> lbk5
lbk5 -> lbk4
lbk6 -> lbk7
lbk7 -> lbk6
