Merge branch 'net-phy-realtek-move-PHY-resume-delay-from-MAC-to-PHY-driver'

Heiner Kallweit says:

====================
net: phy: realtek: move PHY resume delay from MAC to PHY driver

Internal PHY's from RTL8168h up may not be instantly ready after calling
genphy_resume(). So far r8169 network driver adds the needed delay, but
better handle this in the PHY driver. The network driver may miss other
places where the PHY is resumed.
