Subject: [PATCH net-next] net: atlantic: add set_power to fw_ops for atl2 to fix wol
Aquantia AQC113(C) using ATL2FW doesn't properly prepare the NIC for
enabling wake-on-lan. The FW operation `set_power` was only implemented
for `hw_atl` and not `hw_atl2`. Implement the `set_power` functionality
for `hw_atl2`.
Tested with both AQC113 and AQC113C devices. Confirmed you can shutdown
the system and wake from S5 using magic packets. NIC was previously
powered off when entering S5. If the NIC was configured for WOL by the
Windows driver, loading the atlantic driver would disable WOL.

Notes:
The changes within this patch were originally written by developers from
Marvell (formerly Aquantia) as mentioned in the patch trailer using
Co-developed-by. Adding the `set_power` function for ATL2FW was one of
many changes that were released as part of the v2.4.7 update for the
vendor atlantic driver. I have only copied the functions necessary to
enable WoL and modified the required functions to work with the upstream
Linux kernel and followed netdev conventions (reverse xmas).
The latest driver from Marvell can be obtained from the following page,
https://www.marvell.com/support/downloads.html, resulting in the link,
https://www.marvell.com/content/dam/marvell/en/drivers/07-18-24_Marvell_Linux_2.5.12.zip
An earlier version of the driver was published by Aquantia on GitHub at
https://github.com/aquantia/AQtion. The community has been using this
GitHub project to discuss issues with the atlantic driver (even those
not present in the GitHub repo), including the lack of WoL support in
the upstream Linux kernel.
