ar8216: factor out PHY init code into a generic function
PHY init code in the switch-specific hw_init functions is mainly identical. Factor it out into a generic ar8xxx_phy_init function. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Felix Fietkau <nbd@openwrt.org> SVN-Revision: 43331
