airoha: an7583: add additional comments on EVB board
On the Airoha AN7583 EVB there are 2 Aeonsemi AS21xxx PHY but only the
one connected to Serdes Ethernet is usable as the other connected to
Serdes PON is not actually HW connected (as the serdes is connected to
the BOSA port)
Add comments and disable the relevant PHY.
