net: sparx5: start the TOD counters on non-PTP lan969x variants

Browse source

Currently the base non-PTP-capable lan969x variants don't forward any
Ethernet frames:

  $ ip link set eth10 up

  $ ip addr add 10.0.0.54/24 dev eth10

  $ ping 10.0.0.1
  PING 10.0.0.1 (10.0.0.1): 56 data bytes

  --- 10.0.0.1 ping statistics ---
  7 packets transmitted, 0 packets received, 100% packet loss

  $ cat /proc/interrupts | grep fdma
    20:          0  GIC-0  120 Level     sparx5-fdma

  $ ip -s link show dev eth10
      RX:  bytes packets errors dropped  missed   mcast
           20828     102      0       0       0      72
      TX:  bytes packets errors dropped carrier collsns
               0       0      0       0       0       0

Testing showed that starting the domain 0 TOD counter gets networking
working again, but start all three for consistency with the PTP variants.
