msf2: Unbreak device-list-properties for "msf-soc"

Browse source 
Watch this:

    $ qemu-system-aarch64 -M ast2600-evb -S -display none -qmp stdio
    {"QMP": {"version": {"qemu": {"micro": 50, "minor": 0, "major": 5}, "package": "v5.0.0-2464-g3a9163af4e"}, "capabilities": ["oob"]}}
    {"execute": "qmp_capabilities"}
    {"return": {}}
    {"execute": "device-list-properties", "arguments": {"typename": "msf2-soc"}}
    Unsupported NIC model: ftgmac100
    armbru@dusky:~/work/images$ echo $?

This is what breaks "make check SPEED=slow".

Root cause is m2sxxx_soc_initfn()'s messing with nd_table[] via
qemu_check_nic_model().  That's wrong.

We fixed the exact same bug for device "allwinner-a10" in commit
8aabc5437b "hw/arm/allwinner-a10: Do not use nd_table in instance_init
function".  Fix this instance the same way: move the offending code to
m2sxxx_soc_realize(), where it's less wrong, and add a FIXME comment.

Fixes: 05b7374a58 ("msf2: Add EMAC block to SmartFusion2 SoC")
