"wol-arp-packet" property enables WOL with ARP packet.
It is an extension to "magic-packet for WOL.

It not clear why this is needed. Is this not a standard feature of the
IP? Is there no hardware bit indicating the capability?

WOL via both ARP and Magic packet is supported by the IP version on ZU+ 
and Versal. However, user can choose which type of packet to recognize 
as a WOL event - magic packet or ARP. The existing DT binding already 
describes one entry for wol via magic packet. Hence, adding a new packet 
type using the same methodology.

And why would this be board-level configuration? This looks like OS policy.
