net: dsa: microchip: ksz9477: Add Wake on Magic Packet support
Introduce Wake on Magic Packet (WoL) functionality to the ksz9477
driver.
Major changes include:
1. Extending the `ksz9477_handle_wake_reason` function to identify Magic
Packet wake events alongside existing wake reasons.
2. Updating the `ksz9477_get_wol` and `ksz9477_set_wol` functions to
handle WAKE_MAGIC alongside the existing WAKE_PHY option, and to
program the switch's MAC address register accordingly when Magic
Packet wake-up is enabled. This change will prevent WAKE_MAGIC
activation if the related port has a different MAC address compared
to a MAC address already used by HSR or an already active WAKE_MAGIC
on another port.
3. Adding a restriction in `ksz_port_set_mac_address` to prevent MAC
address changes on ports with active Wake on Magic Packet, as the
switch's MAC address register is utilized for this feature.
