net: phy: add genphy_c45_read_eee_abilities() function
Add generic function for EEE abilities defined by IEEE 802.3
specification. For now following registers are supported:
- IEEE 802.3-2018 45.2.3.10 EEE control and capability 1 (Register 3.20)
- IEEE 802.3cg-2019 45.2.1.186b 10BASE-T1L PMA status register
(Register 1.2295)
Since I was not able to find any flag signaling support of these
registers, we should detect link mode abilities first and then based on
these abilities doing EEE link modes detection.
Results of EEE ability detection will be stored into new variable
phydev->supported_eee.
