net: phy: make of_set_phy_supported work with genphy driver
of_set_phy_supported allows overwiting hardware capabilities of a phy with values from the devicetree. of_set_phy_supported is called right after phy_device_register in the assumption that phy_probe is called from phy_device_register and the features of the phy are already initialized. For the genphy driver this is not true, here phy_probe is called later during phy_connect time. phy_probe will then overwrite all settings done from of_set_phy_supported Fix this by moving of_set_phy_supported to the core phy code and calling it from phy_probe.
