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.
