31afd6bc55 net: phy: pass PHY driver to .match_phy_device OP 
Pass PHY driver pointer to .match_phy_device OP in addition to phydev.
Having access to the PHY driver struct might be useful to check the
PHY ID of the driver is being matched for in case the PHY ID scanned in
the phydev is not consistent.

A scenario for this is a PHY that change PHY ID after a firmware is
loaded, in such case, the PHY ID stored in PHY device struct is not
valid anymore and PHY will manually scan the ID in the match_phy_device
function.

Having the PHY driver info is also useful for those PHY driver that
implement multiple simple .match_phy_device OP to match specific MMD PHY
ID. With this extra info if the parsing logic is the same, the matching
function can be generalized by using the phy_id in the PHY driver
instead of hardcoding.

Rust wrapper callback is updated to align to the new match_phy_device
arguments.

Realtek RTL8211F has a "PHY-mode" EEE support which interferes with an
IEEE 802.3 compliant implementation. This mode defaults to enabled, and
results in the MAC receive path not seeing the link transition to LPI

HWMON support has been added for the RTL8221/8251 PHYs integrated together
with the MAC inside the RTL8125/8126 chips. This patch extends temperature
reading support for standalone variants of the mentioned PHYs.

I don't know whether the earlier revisions of the RTL8226 also have a
built-in temperature sensor, so they have been skipped for now.

Tested on RTL8221B-VB-CG.
