net: phy: c45: add setup and read master/slave helpers
This patch adds two static helpers in drivers/net/phy/phy-c45.c to
configure and read back master-slave roles for non BASE-T1 Clause 45
PHYs via the 10GBASE-T AN control/status registers.
These helpers are wired into genphy_c45_config_aneg() and
genphy_c45_read_status(). This changes the observable ethtool output
for drivers using the generic c45 read path.
