net: dsa: microchip: implement .{get/set}_wol only if needed

All the KSZ switches use common {get/set}_wol operations while only the
ksz9477 and the ksz87xx families really support it. These operations are
optional so there is no point implementing them to return -EOPNOTSUPP.

Remove the {get/set}_wol callbacks from the switch operations for the
ksz88xx, the ksz8463 and the lan937x families.
Remove the family check from the common {get/set}_wol implementation.

Note that is_ksz9477() is only true for the KSZ9477 so this change will
also add WoL support for the other switches using the
ksz9477_switch_ops. I checked their datasheet, they implement the same
PME_WOL registers, at the same addresses, so this should go fine.
Modify the ksz_wol_pre_shutdown() initial check to ensure consistency in
the WoL handling for these non-KSZ9477 switches using ksz9477_switch_ops.
