[net-next,v1,0/4] net: phy: add Applied Micro QT2025 PHY driver

This patchset adds a PHY driver for Applied Micro Circuits Corporation
QT2025. The 1-3th patches simply add more support functions for the
PHYLIB Rust bindings, which are necessary for the driver (the fourth
patch).

QT2025 PHY support was implemented as a part of an ethernet driver for
Tehuti Networks TN40xx chips. Multiple vendors (DLink, Asus, Edimax,
QNAP, etc) developed adapters based on TN40xx chips. Tehuti Networks
went out of business but the drivers are still distributed with some
of the hardware (and also available on some sites).

The original driver handles various PHY hardware (AMCC QT2025, TI
TLK10232, Aqrate AQR105, and Marvell MV88X3120, MV88X3310, and
MV88E2010). This driver is extracted from the original driver and
modified to a PHY driver in Rust.

This driver and a modified ethernet driver using PHYLIB have been
tested with Edimax EN-9320SFP+ 10G network adapter.

Note that the third patch adds Firmware API for PHY drivers. Firmware
API isn't specific to PHY drivers. I think that it would be
appropriate to add the feature to rust/kerel/device.rs. However,
recently drm developers have worked on that area actively so I added
it to phy.rs for now to avoid conflict (I assume that this patchset
would be merged via netdev tree and drm work would via rust or drm
tree). Once things calm down a bit, I'll move this feature (I suspect
that drm also needs rust bindings for Firmware API too).
