net: phy: Add dts support for Motorcomm yt8531s gigabit ethernet phy
Add dts support for Motorcomm yt8531s gigabit ethernet phy. Change yt8521_probe to support clk config of yt8531s. Becase yt8521_probe does the things which yt8531s is needed, so removed yt8531s function. This patch has been verified on AM335x platform with yt8531s board.
