Summary

Advertise IFCAP_WOL_MAGIC when PCI power management is available
and enable it by default. On suspend or shutdown, rge_setwol()
enables the WOL_MAGIC and WOL_LANWAKE bits in CFG3/CFG5, disables
the RXDV gate, and enables PM so the NIC stays powered to watch
for magic packets.

Update rge.4 to document WoL support.

Test Plan

Tested on FreeBSD 16.0-CURRENT bare metal with Realtek RTL8125 on a Gigabyte B650 Gaming X AX motherboard.
Sending a magic packet with wol from my Arch Linux laptop wakes up the FreeBSD desktop.

hi! i'm trying to put as much hardware specific code into if_rge_hw.c to hopefully make it easier to keep whole hardware-specific routines in sync with openbsd.

Would you mind updating your diff to push the wol code back into if_rge_hw.c and call it there? thanks!
